1998
NEW FOR 1998:
Fork travel increase of 9mm and friction-reducing compression and damping refinements.
Rear shock stroke-increase of 5.8mm results in an increase of rear axle stroke by 10.2mm. New rear spring rate and rear linkage ratio.
Revised frame geometry includes steeper caster, shorter trail, and shorter wheelbase.
Frame has relocated shock mount, new chain-roller location, and improved welding methods at headpipe, shock mount, and engine bracket areas.
Subframe uses thinner-walled design and a new mounting location to reduce weight and maintain strength.
New swingarm features a 1.5mm-thicker cross-body for improved rigidity and balance.
Redesigned countershaft provides a more precise fit with drive sprocket.
Stainless steel clutch cable for longer life.
Seat foam density improved.
ENGINE:
Liquid-cooled 2-stroke single cylinder engine with 66.4mm x 72.0mm bore & stroke and 8.7:1 compression ratio.
Map-type digital electronic ignition system monitors engine speed to provide optimal timing for faster, stronger response during hard acceleration.
Power Jet Control (PJC) carburetor features solenoid-controlled auxiliary main jet that opens at low rpm for stronger, more linear response and improved traction out of corners.
Steel water-pump gear.
Large-volume single radiator.
CHASSIS / SUSPENSION:
Aluminum twin-spar frame features dual box-section spars and downtubes, and compact forged pivot-plates for light weight and rigidity. Main frame and swingarm have variable wall-thickness for ideal combination of light weight and strength.
Light, tapered aluminum box-section swingarm.
Rear axle features integrated collars.
Rear disc brake features low-positioned caliper and thin, large-diameter, 240mm rotor.
Lightweight 47mm inverted Showa cartridge fork features 12.4 inches of travel, and 18-position rebound damping adjustability in addition to 20 clicks of compression damping adjustability.
Inner surface of front fork outer-tubes and rear damper case are molybdenum-coated for low friction.
Pro-Link® single-shock rear suspension system features a fully adjustable Showa 46mm rear damper and 12.9 inches of wheel travel. Separate low-speed and high-speed compression damping adjusters.
ADDITIONAL FEATURES:
Wide, cleated, self-cleaning, folding, cast stainless steel footpegs.
Lightweight, ultra-strong chain guide.
Cleated rear brake lever and folding shift lever tip.
Strong, rigid front wheel features large-diameter front axle and wide wheel-bearing span.
Super-light rims, straight-pull spokes and lightweight hubs offer exceptional durability and minimize unsprung weight for optimum suspension action.
