Features and benefits

Key features:

The R1 is the culmination of 50 years of racing experience, combining tremendous power with light weight and excellent handling.Newly retuned Deltabox V® frame, revised forks and a 20mm longer swingarm take R1 handling to the next level.50th Anniversary Special Edition model celebrates Yamaha racing heritage with special badging and classic black andyellow livery.

New for 2006:

GP tech trickles down: Revised rigidity of the main framebetween the engine mounts and steering head, a new, morerigid lower triple clamp, a 20mm-longer swingarm producethe best-handling R1 ever.Shorter valve guides and other revisions increase intake flow and reduce friction, for more powerGold-colored forks look great.Revised clutch boss provides increased oil flow forexcellent durability.

Engine:

Short-stroke 998cc DOHC, 20-valve, liquid-cooled inlinefour-cylinder engineDual-valve fuel injection system uses motor-driven secondarythrottle valves and 32-bit ECU for super-responsive,instantaneous power deliveryTwo-piece ergonomically designed fuel tank carries fuel in the rear section, for good centralization of mass, while the front half contains a Ram-Air-fed airbox for increased power.Lay-down design cylinder head—40 degrees forward —optimizes weight distribution, straightens intake tractsfor improved cylinder filling, and allows frame to pass overinstead of around the engine for great strength and anarrow chassis.Closed-deck cylinder block increases strength and allows anarrow engine in spite of big, 77mm bores.Narrow-angle five-valve combustion chambers produce a highly efficient 12.4:1 compression ratio. Big valves and high-lift cams flow plenty of air.Carburized connecting rods with fractured big ends produce a quick-revving engine with excellent high-rpm durability.High silicon-content ceramic-composite cylinder sleeves ensure great heat dissipation for consistent power delivery and reduced friction.Strong, yet lightweight clutch and close-ratio six-speed gearbox with triangulated shaft layout for great strength, compactness, and quicker accelerationTitanium underseat exhaust system (with stainless steel midpipe and catalyst) contains a titanium EXUP valve for a broad, seamless powerband.High-efficiency curved radiator and an aluminum liquidcooled oil cooler maintain stable operating temperature.Direct ignition coils, dual-electrode spark plugs and highoutput magneto deliver extremely accurate, reliable firing.AC generator behind cylinder block produces a narrow engine with excellent cornering clearance.

Chassis/Suspension:

Overall frame width of only 15.6 inches produces comfortable ergonomics as well as efficient aerodynamic penetration.Controlled Fill die cast, truss-type swingarm is very strong and longer, for optimal traction and feedback.Controlled Fill die cast, detachable aluminum subframe is light, strong and allows easy rear shock access.Dual 320mm front disc brakes; light/strong, forged one-piece radial- mount calipers and Brembo radial-pump front master cylinder with adjustable lever delivers amazing braking power and controllability
