It is built around a 687cc fuel-injected V-Twin engine. The liquid-cooled, four-valve mill has a mildly aggressive 11.5:1 compression ratio. The 90 degree cylinder angle is inherently smooth and keeps the overall height of
The DOHC V-Twin is basically the same as that used in S&T's 650cc sportbikes, so it always feels a little racy. Both the torque and rev characteristics are impressive for a bike in this class. Claimed performance numbers are a respectable 62 horsepower and 47 lb/ft of torque at 8000 rpm.
Power is transferred through the five-speed transmission to a toothed belt final drive. The transmission ratios are wide spread, but there is plenty of grunt to keep the power delivery smooth. The belt drive features an automatic tension adjuster; therefore it is practically maintenance free. The transmission shifts smoothly, although there was a little free play in the shift linkage that I found annoying.
Helping contribute to the wide and low-slung look are the machined aluminum wheels. The front rides on a 120 series 16-inch tire and the rear a 170/80/15. The wheels themselves are a nice blend of machined surfaces contrasted by painted black insets. The single 300 mm floating front disc brake features a four-piston caliper. Out back is a 270 mm disc with a two-piston binder. Braking power is strong, but does require a healthy amount of lever effort. |
