The Kawasaki KX250 is a 2-stroke motocross bike that was introduced in 1974. This bike has been ridden to several AMA Motocross wins, including a number of titles. The 2-stroke KX-250 is no longer sold in the United States due to lack of equipment and need. For the U.S. Market, the KX450F and KX250F was introduced in 2006 and utilizes a 4-stroke engine developed using Formula One technology.

The Honda CBR600F4i was a sport bike[1] produced by Honda from 2001 to 2006.

For the 2001 model year Honda released an upgraded version of the popular CBR600F4 with intentions of becoming more competitive in the middleweight sport bike class. The 370 lb (170 kg) (dry) F4i is a modified F4 with numerous engine, chassis and bodywork changes.History

The single largest change aside from the styling is the addition of high-pressure (50 psi) programmed fuel injection — thus the model designation "F4i". In a number of countries, the bike was sold in both the "normal" and "Sport" variants, the Sport having a two-part seat, no grab rail and no main stand (though the main stand mounting holes remained). Fuel injection allows for more precise fuel metering and delivery over a wider rpm range, while providing better throttle response and reducing emissions. The injectors reside one per cylinder and work with 38 mm throttle bodies. Each injector has four nozzles, and together the injectors add up to five horsepower over the F4.
Weight was also reduced. The rear wheel was made 400 grams lighter, the cush drive 600 grams, and the front wheel 300 grams. The wheel bearings have been moved outward, closer to the fork tubes, and the rotor carriers moved out closer to the brake calipers to reduce weight and to improve rigidity. Each caliper carrier also lost 100 grams. There is additional bracing on the steering head for more response, better feedback and feel from the front end. The suspension has also been tweaked with less high-speed damping and a little more low-speed damping. The wheelbase is five millimeters shorter than its predecessor, with a 5.9-percent increase in overall rigidity.
Additional engine changes include a lighter camshaft sprocket and increased valve spring pressure (two springs per intake valve) which allow for higher revving. There are new piston rings that slide with less friction and increased internal engine oil flow. Redline is now 14,200 rpm, 700 rpm higher than the previous year's F4. To increase the bike's pulling capabilities at high speeds, 5th and 6th gears have been shortened slightly and the rear sprocket was enlarged from 45 teeth to 46. The oiling holes in the camshafts have been enlarged by 0.5 mm (to 2.5 mm) and piston ring friction has been decreased to aid cooling at the higher rev ceiling. Spring pressures on the intake and exhaust valves have been increased to avoid valve float. Also, there are now two valve springs (inner and outer) on the intake side instead of the single item that resides on the exhaust side.
In 2003, Honda introduced the CBR600RR, a higher-performance, race-ready, super-sport middleweight, while continuing to manufacture the popular F4i which appealed to those willing to sacrifice a little performance to gain a more comfortable riding position, as well as an engine configuration better suited to everyday riding. The F4i remained available for three more years before being discontinued, with the 2006 model being the final one to be released. In 2006 the Honda CBR600F4i retailed for US$8,499. No major updates were made in these final years except for color scheme changes.

[edit]Styling

Honda included some styling changes due to criticisms of the F4 being too bland[citation needed]. The 2001 US F4i features a new subframe which raises the seat by five milimeters and an improved two-tier seat allows for more storage room in the rear compartment. The new tail unit has less padding and a higher perch for the passenger. The F4i’s tail-light is smaller with a new dual-bulb configuration. The F4i features a new dash layout with a large analog tachometer. The new LCD digital display includes a speedometer, odometer, clock, engine temperature read-out, amber shift light, and trip meters.
The F4i's new bodywork carries a more 'racy' look and provides a 3% reduction in drag. It also houses a new dual headlight front cowl design which uses 40% brighter H7 bulbs compared to the old H4 bulbs. The headlights are dual multi-reflector units covered by a one-piece flexiglass lens. The turn stalks are shorter and the mirrors are now positioned higher and closer to the rider. The elimination of carburetors allowed for a slightly larger air box and a larger fuel tank (4.8 us gallons / incl. 0.9 reserve) complete with a delayed fuel level sensor to prevent false readings when the bike is at an angle.
In 2004 Honda replaced the black frame with one in silver and a banana seat due to complaints of comfort and to differentiate the F4i from the 600RR. This model is the same as the CBR600F1 and onwards that was sold in the UK from 2001.
Two UK versions of the F4i were released in 2001. The CBR600F F1 and onwards had the banana style seat found on pre PGM FI bikes whilst the CBR600F FS1/FS2 (the F sport) were sold with the two tier seat units, black frames and various other performance upgrades as found in the US models. The F sport was discontinued upon the arrival of the CBR600RR in 2003.

The Honda CR-Z is a compact hybrid electric automobile manufactured by Honda and marketed as a "sport hybrid coupe."[3]The CR-Z combines a hybrid gasoline-electric powertrain with traditional sports car[4] elements - most notably having a 2+2 seating arrangement and a standard manual transmission. The CR-Z is regarded as the spiritual successor to the second generation Honda CR-X in both name and exterior design.[5][6]
In the U.S., it is one of the least polluting vehicles available and is rated as an Advanced Technology Partial Zero Emissions Vehicle (AT-PZEV) as defined by the California Air Resources Board (CARB). The CR-Z is the only gasoline-electric hybrid model offered by any automaker that can be equipped with a manual transmission (except for older 2001-2005 models of Insight and Civic Hybrid).[7]
The CR-Z is the sixth unique version of Honda's IMA technology since the technology was first launched in the first generation Insight 3 door hatchback.[3] Sales of the CR-Z began in Japan in February 2010.[8] Sales in the U.S. began in August 2010.[9]

The design and production of the CR-Z followed two other Honda hybrid concept cars: the Honda Remix, introduced at the 2006Los Angeles Auto Show, and the Honda Small Hybrid Sports, introduced at the 2007 Geneva Motor Show.[10]History

The Honda CR-Z was first introduced as a concept vehicle on October 23, 2007 at the 2007 Tokyo Motor Show. Honda explained the name "‘CR-Z’ stands for ‘Compact Renaissance Zero’— an expression intended to capture the idea of a renaissance in the design of compact cars that begins anew from fundamentals."[11] At the show, CEO Fukui stated that aproduction model is "in the works" and that the car was intended to be "sporty, incredibly efficient and inexpensive".[12]
The CR-Z was first shown in America at the 2008 Detroit North American International Auto Show.[13] In the 2009 Tokyo Motor Show, Honda displayed a revised "CR-Z Concept 2009".[14] In January 2010, Honda introduced the production CR-Z at the 2010North American International Auto Show in Detroit.[15]
Automotive News reported in June 2010 that since its debut at the Detroit Auto Show, the CR-Z Web site has had 1 million hits.[16] Honda has been promoting the 2011 model from the Facebook game Car Town.[17]

[edit]Development

The project leader, Norio Tomobe, worked previously as chief engineer on Mobilio Spike and Elysion.
The basic concept of CR-Z is said to create a fun-to-drive sports car driving characteristics Honda aspired from that of the Lotus Elise, as well as the Mini and Volkswagen Scirocco. In a video, Torikai, the chief chassis engineer of CR-Z, explained that during the development process “this car was brought to Europe at each prototype stage to be tested under various road conditions to evaluate whether the desired performance had been achieved.”
Norio Tomobe believes the hybrid element will make it a sports car without guilt.[18]

[edit]Powertrain


Rear view of the Honda CR-Z.
The CR-Z is powered by a 1.5 L (92 cu in) i-VTEC SOHC inline-4 engine, designated as LEA, with Honda's Integrated Motor Assist (IMA) hybrid-electric system.[19] A six-speed manual transmission is standard equipment and a continuously variable transmission (CVT) is available. The system delivers a combined peak output of 122 bhp (91 kW; 124 PS) at 6000 rpm and 128 lb·ft (174 N·m) at 1000 to 1500 rpm (123 lb·ft (167 N·m) on CVT-equipped models). The gasoline motor itself contributes only 111 bhp (83 kW; 113 PS) at 6000 rpm and 106 lb·ft (144 N·m) at 4800 rpm. An early road test of a Japanese-market CR-Z resulted in 0-60 mph in 10.5 seconds and the quarter mile in 17.6 seconds.[20] Inside Line performed the same 0-60 mph test in 8.8 seconds, and Motor Trend, in 8.3 seconds.[21][22]
On 2012 Nov 21, Honda released to the US market the 2013 CR-Z which, other than minor cosmetic changes, included a more powerful electronic motor (going from 10 to 15 kilowatts), and a new, higher voltage (144V), lithium ion battery pack. The 2013 CR-Z delivers a combined peak output of 130 horsepower at 6,000 rpm and 140 pound-feet of torque (127 pound-feet on CVT-equipped models), a gain of eight horsepower and 12 pound-feet of torque (4 pound-feet on CVT equipped models). A new Plus Sport System is standard. If the battery is more than 50 percent charged and the CR-Z is traveling over 19 mph, the driver can press the "S+" button on the steering wheel to deliver increased acceleration for up to five seconds. Manual-transmission versions also receive both a larger clutch and a new lower final drive ratio. EPA-rated fuel economy figures increased by 1 mpg city for CVT equipped models, and 1 mpg highway for those with the six-speed manual transmission.[23]

[edit]Fuel economy

Japanese fuel economy ratings are 4.0 litres per 100 kilometres (59 mpg-US) for CVT and 4.4 litres per 100 kilometres (53 mpg-US) for MT in 10•15 mode; and 4.4 litres per 100 kilometres (53 mpg-US) for CVT and 4.9 litres per 100 kilometres (48 mpg-US) for MT in JC08 mode.[8]
The 2011 CR-Z U.S. EPA ratings are 31 miles per US gallon (7.6 L/100 km; 37 mpg-imp) for city and 37 miles per US gallon (6.4 L/100 km; 44 mpg-imp) for highway with manual transmission. The model with CVT transmission has a rating of 35 miles per US gallon (6.7 L/100 km; 42 mpg-imp) for city driving cycle and 39 miles per US gallon (6.0 L/100 km; 47 mpg-imp) for highway.[24]
When comparing fuel economy to the CR-Z's older cousin, according to fueleconomy.gov, the 1988 gasoline-powered Honda CR-X HF had an EPA rating of 41 miles per US gallon (5.7 L/100 km; 49 mpg-imp) city driving, and 49 miles per US gallon (4.8 L/100 km; 59 mpg-imp) highway driving.[25] It is ranked number four on 2011 EPA top ten list of fuel efficient vehicles for CVT equipped model and number ten for manual transmission equipped model.[26]

[edit]Handling

Road and Track reports that the handling is good, with mild under-steer and firm suspension, possibly in spite of the front wheel drive and the space-saving MacPherson strut front suspension, neither of which is typical of full-out sports cars[citation needed].

[edit]Price and sales by region

[edit]Japan

Sales of the CR-Z began in Japan on February 26, 2010 at a starting price of ¥2.27 million (~US$25,340) before any government subsidies.[8][27] Honda announced that in less than one month it has received orders for more than 10,000 vehicles, far exceeding its sales forecast.[28]
As of the end of August 2010, more than 19,000 CR-Z were delivered and sales orders received are three times higher than expected, which led to Japanese media comparing its success with the NSX in the 1990s, another sports car from Honda.[29] In an interview in early February 2011, a Honda executive disclosed that Honda produces around 200,000 hybrids a year in Japan.[30]

[edit]North America


Profile view of CR-Z
Sales in North America started on August 24, 2010.[9][24] The 2011 CR-Z is offered in three trim levels: base, EX, and EX with navigation. The base CR-Z starts at US$19,950, the CR-Z EX starts at US$21,510 and the EX with navigation trim is priced at US$23,310.[31] The CR-Z pricing is similar to the Honda Insight and has a lower price than the market leader Toyota Prius.[31]
After its launch in late August 2010, there were 3,349 Honda CR-Z sold as of end of October, 2010. It ranked as the fourth most sold hybrid in the U.S. for September and October of that year.[32] U.S. sales for year 2010 reached 5,249 units, and ranked 11th in hybrid sales for that year.[33] For year 2011 cumulative sales of the CR-Z in the U.S. reached 9,635 units through August, ranking number four inhybrid sales in 2011 and outsold only by the Hyundai Sonata Hybrid, Honda Insight, and Toyota Prius.[34]
In addition to commercials airing during sporting events, Honda held a marketing competition available to universities throughout the United States. This competition allowed students to create public relations and social media campaigns for the vehicle.[35] A team fromSyracuse University won first place in the competition, followed by runners-up New England School of Communications and University of LaVerne.[36]

[edit]Europe

The CR-Z was launched in the European market in mid-2010[37] after having been revealed at the 2010 Geneva Motor Show. The price in the United Kingdom starts fromGB£16,999.[38]

[edit]South Africa

Sales in South Africa are scheduled to begin on the 30th of August 2010 at a price of R299,999 (~US$38,960) making it slightly cheaper than the entry level Prius for the South African market.[39]

[edit]Malaysia

The CR-Z was launched for the Malaysian market on 3 November 2011, with a price tag of RM115,000 (on-the-road with insurance), which made it the first in Southeast Asia to offer the three-door hybrid.[40][41] Within a month, Honda has received over 300 orders, over three times its target.[42] The introduction of the CR-Z was a result of the 2012 Malaysian Budget that extended the full import duty and excise duty exemption to imported hybrid vehicles and electric cars to 31 December 2013.[43] The 6-speed manual model has been offered, with plans to bring in the CVT version in 2012; in addition to white, three more colours will be offered by early 2012.[42]

[edit]Australia

It was reported that Honda would release the CR-Z hybrid coupe in the Australian market in the middle of 2011.[44] It appeared in the 2011 Australian International Motor Show in June but the launch was delayed by the earthquake and tsunami in Japan.[45] It was launched in Australia in December 2011, starting from A$34,990 (before on-road costs) for the Sport grade with a 6-speed transmission.[46]

[edit]New Zealand

It was launched in New Zealand in December 2011, starting from NZ$44,900.[47]

[edit]Racing

Two Honda Performance Development CR-Z Racers entered the 25-hour of Thunderhill endurance race held on December 4–5, 2010 at Willows, California. The car, first shown to the public at 2010 SEMA Show, is fully stripped down with lowered suspension. A turbo charger is bolted to the engine raising output to 175 hp (130 kW) and 155 lb·ft (210 N·m) of torque, furthermore, the Integrated Motor Assist setup is modified utilizing components from Mission Motors[48] and a push-to-pass function is added, making a total of 200 hp (149 kW) and 175 lb·ft (237 N·m) of torque when the button is pressed.[49][50] One of the two entrants battled from a near 10-lap deficit to finish second in the Endurance 3 class, after suffering early in the race from two five-minute "stop-and-hold" penalties caused by refueling problems. The other entrant scored pole position of the class but failed to finish the race.[51][52] The Honda CR-Z was one of the most showcased cars during the SEMA show earlier in the year and one of the cars produced 533 hp (397 kW). This is what the hybrid engine could withstand in terms of power.[53]
