Engine
-
Nearly every functional part of the engine is new
- From the cylinder body, cylinder head, piston, piston pin, connecting rod, crankcase and expansion chamber, to a revised cylinder port shape and updated cylinder port timing.
- It's a change that is immediately apparent at the first crack of the throttle and throughout the entire rpm range.
-
Updated intake design allows for a straighter, more efficient draw of air into the intake tract.
-
Patented YPVS™ combines crisp, hard-hitting bottom-end acceleration with strong mid-range and top-end.
-
Revised six-speed, close-ratio transmission has wider transmission gear tooth width and new, optimized gear ratios for maximum performance.
-
Patented YPVS™ combines crisp, hard-hitting bottom-end acceleration with strong mid-range and top-end.
-
Digital CDI system delivers precise spark and monitors engine speed to ensure optimal timing
- Resulting in faster, stronger response during hard acceleration
-
Large-capacity radiator features a 10-row core with blacked-out louvers to deliver an aggressive look and maximum cooling efficiency.
-
Close-ratio, 6-speed transmission uses optimized gear ratios.
- ratios are matched to engine output for maximum performance
- optimal hook-up for outstanding acceleration & corner-exiting power
- transmission features "involute splines" for smooth, positive shifting even under power
-
Yamaha's patented YPVS system.
- features a slide (guillotine) type power valve that provides the benefits of both solid, low-rpm power delivery combined with a strong top-end punch. This system varies the exhaust port height and timing based on engine rpm.
-
New high-precision Hitachi Astemo® Keihin PWK38S carburetor
- Features a power jet, throttle position sensor and 3D-map-controlled CDI unit for precise ignition timing.
- The result is clean, crisp throttle response, superior rideability and excellent over-rev character.
-
6-petal, carbon fiber reed design.
- for stronger high-rpm performance with greater over-rev capacity
-
Works-style clutch lever & race-spec "barrel adjuster."
- easy lever pull
- for on-the-fly clutch adjustments

Chassis/Suspension
- Race-proven, highly developed aluminum semi-double cradle frame is engineered to provide just the right amount of strength and flex for the perfect balance of stability and cornering performance.
- Removable aluminum rear subframe is constructed of square-section tubing for reduced weight.
- A new flatter seat and more narrow fuel tank design, along with smoothly integrated body panels and slimmer shroud width, combine to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for increased control and confidence.
- An updated lightweight braking system features larger front pistons, a more rigid caliper, a redesigned 270mm front rotor with a 30% increase in pad contact area and higher friction pad material, all combining to provide exceptional braking power and feel.
- The redesigned rear rotor maintains the same braking power while dropping outer diameter from 245mm to 240mm, further reducing unsprung weight with no compromise on performance.
- Industry-Leading KYB® Fork
- The Speed-Sensitive System 48mm inverted KYB® fork includes a leaf spring in the mid-speed valve for more precise damping and increased performance and comfort, while offering up 11.8 inches of travel.
- Advanced KYB® Shock
- Revised fully adjustable KYB® rear shock features reduced-friction Kashima Coat™ internals, separate adjusters for high- and low-speed compression damping, a full lock oil rebound system for increased comfort, and 12.4 inches of travel. It all adds up to fantastic rear wheel control and class-leading capability.
- Race-Ready Tires
- Premium Bridgestone® Battlecross X20 tires offer strong cornering grip and race-developed performance.
