W800 against other retro bikes
At $10,699 it is $2,100 more than Yamaha's XSR700 at $8,599 and $3,296 below Triumph's Bonneville T120 at $13,995. The T120 weighs 513.7 lb against the W800's 498.3 lb. The W800 has the smallest power figure of the three, which is part of the retro character, and it has the most old-school engine layout, air-cooled with a long stroke.
Riding numbers and equipment
The W800's long-stroke design gives its torque low in the rev range: 46.5 lb-ft at 4,800 rpm, against 51 hp at 6,500. The compression ratio of 8.4:1 is low by modern standards and suits the air-cooled design. Ignition is a TCBI unit with digital advance, ABS is the only electronic aid, and the tank is 4.0 gal.
At 498.3 lb curb it is heavy for a 51 hp bike, but the 31.1 in seat is accessible. The sealed chain and five-speed gearbox are simple by design, in keeping with the retro brief.
Choosing the W800
The W800 is a choice for a rider who wants the look and sound of a 1960s twin and is willing to pay $10,699 for an air-cooled bike with modest performance. It is not the fast option; Yamaha's XSR700 has a stronger engine and costs $2,100 less. If you value the vertical twin's sound, the low compression ratio and the styling, sit on one at a dealer.
W800 against the Bonneville T120 and XSR700
Triumph's Bonneville T120 is the classic-styled rival, and Yamaha's XSR700 is the modern retro at a lower price.
Kawasaki W800 — specification referenceTotal Motorcycle says the large 19-inch front wheel and 18-inch rear give a balance of relaxed handling, light turning and excellent straight-line performance while keeping the vintage look, and that although thoroughly modernized it gives the classic feel of a 1960s machine with the pulse of a throaty retro air-cooled vertical twin.
The write-up adds that the power and performance features combine with authentic Kawasaki W1 styling, and that stopping comes from ABS brakes with a large 320 mm front disc and 270 mm rear disc.
