FEATURES & BENEFITS
New for 2004:
- All-new, lightweight 48mm inverted Kayaba cartridge fork features 11.8 in. of travel with compression and rebound damping adjustability. Special coating on fork reduces stiction while giving “factory” appearance.
- Lightweight front and rear calipers with aluminum pistons and revised front master cylinder combined with 250mm fully floating front and 245mm rear disc deliver strong stopping power with progressive control and feel.
- All-new, upper triple clamps feature an anodized finish for “factory” look.
- All-new, “gripper-style” seat cover offers excellent feel and control.
- All-new, wide, cleated, folding titanium footpegs are lightweight and provide excellent comfort, grip and ground clearance.
- Redesigned clutch (kick pinion gear now separated from the primary driven gear) for smoother clutch engagement.
- Revised digital CD ignition system delivers ultra-precise spark and timing for faster, stronger engine response during hard acceleration and less kickback during starting.
Engine:
- Liquid-cooled, 449cc, 5-valve, DOHC, 4-stroke with titanium valves features 63.4mm stroke delivering flat, broad torque curve (for instant hook-up) with high over-rev capacity and crisp, linear throttle response.
- 39mm Keihin FCR flat-slide carburetor with throttle position sensor (TPS) delivers ultra-precise fuel/air mixing and instant throttle response.
- Lightweight crankshaft keeps inertial mass to a minimum for faster-revving low-rpm response.
- Piston features short skirt and smaller pin boss diameter to help reduce weight.
- Lightweight titanium valves and load-reduced springs are super-light, minimizing reciprocating mass for fast-revving, hard-hitting power delivery across the rev range.
- Additional weight-saving engine features include: small-design cam chain tensioner and oil pump; aluminum oil hose; all-titanium exhaust header, flange, bracket and heat shield; and light CDI ignition unit.
- Primary kickstarting (with automatic decompression and convenient handlebar-mounted hot start lever) ensures easy restarts.
- Redesigned airbox features all-new retaining bracket for improved sealing.
- Smooth-shifting 4-speed transmission delivers engine’s potent powerband to the ground with maximum efficiency and hook-up.
- Large-capacity radiator provides outstanding cooling efficiency.
- Trick, works-style clutch lever features oversize barrel adjuster for easy, on-the-fly adjustability of lever/cable play.
Chassis/Suspension:
- Super-strong frame is lightweight and laterally rigid for minimal flex and razor-sharp handling.
- Tapered swingarm is light and rigid for compliant rear suspension action.
- Recalibrated front fork settings deliver improved damping force with less bottoming for a smoother, more compliant overall stroke.
- More weight savings come via two-piece (part aluminum, part plastic) engine protector plates and thin-walled engine guard construction.
- Removable aluminum rear subframe constructed of square-section pipe for light weight and easy maintenance.
- Rear suspension system features fully adjustable Kayaba shock with 12.4 in. of travel and separate adjusters for high- and low-speed compression damping.
- Lightweight front wheel hub reduces unsprung weight and increases durability.
- Premium Dunlop 739 knobbies offer unbeatable, competition-spec traction and excellent wear.
- Lightweight 21 in. front and 19 in. rear Excel rims are exceptionally durable and reduce unsprung weight.
Additional Features:
- Cleated rear brake lever and folding shift lever tip offer superb grip and excellent durability.
- Repackable exhaust silencer.
- Durable, comfortable handlebar grips.
- Stainless steel clutch cable for longer life.
