Chassis bits
The "hang-support" frame on this motorcycle allows a lower engine placement and center of gravity while pro-
viding excellent rigidity for precise handling. Cornering clearance is also enhanced. The trailing-axle front sus-
pension performs superbly. The axle placement helps to maintain a short wheelbase, allowing quick, sporty
handling. Yamaha's proven Monoshock rear suspension provides the excellent handling and comfort charac-
teristics for which it is famous. The spring preload is adjustable to five settings.
