Product description

All-new Engine higher performing and more durableHigher performing and more durable
249cc, liquid-cooled, four-stroke, four-valve, DOHC engine delivers hard-hitting power from mid- to high-rpm
Engine oil capacity decreased from 1.5L on previous model to 1.3L, reducing overall weight and mechanical losses
New Top EndNew cylinder head has revised intake ports for improved performance at all rpm, especially in the high-rpm range
Special coating applied to the intake port cores during the casting process gives the intake ports extremely smooth surfaces and increased intake efficiency across the rev range
Head gasket now silicon coated for improved sealing
New cam chain tensioner spring reduces mechanical loss by approximately 30 percent
New Intake and Exhaust ValvesFormed from a new, highly rigid, titanium material, the lightweight 31mm intake and 25mm exhaust valves reduce reciprocating weight and offer greater high-rpm reliability
Ultra-strong valves have extremely thin valve stems on par with those found in supersport machines with the intake valves featuring 0.25mm thicker heads for increased strength
New Titanium Exhaust Pipe- Tapered, expanding from approximately 35 to 45mm for better throttle response and performance at all rpm - New silencer body shape to meet 99dB AMA noise regulations
New Crankshaft BalanceA revised crank web significantly increases the crankshaft balance efficiency; its now on par with the factory racers
Results in reduced engine vibration, smoother power delivery and increased performance in the mid-high rpm range
Better CoolingNew 6.4mm wider radiators have a 6 percent larger capacity than previous model
Very slim, high-capacity Denso radiators feature tightly packed cores and a fin design deliver superior cooling efficiency for excellent heat dispersion
Radiator louvers increased from three to four and decreased in size and angle for less overlap and higher air flow
Revised cylinder head water jacket routes coolant via the front of the cylinder head for a more even cooling performance
Improved TransmissionRatchet drive shift mechanism replaces the previous models gear driven system for improved shift feel and durability
Improved feel at the clutch lever by integrating the clutch cable holder with the crankcase
Increasing the interval between gear shafts 1 mm further allows stronger gears to be used
KX450F type crankcase oil filter added
Relocated scavenge oil filter screen (with new shape) can be accessed without splitting the crankcases, facilitating easier maintenance
New clutch and generator covers for increased rigidity and better crash survivability
New Aluminum Perimeter FrameFrame has a new 6 mm slimmer overall width main spars shape
narrowing near the bend below the seat for a riding position, then widening at the ankles to offer better grip
Newly designed main, lower and gusset pieces around the fuel tank with revised cross sections
Rigidity increased by moving upper engine mounts to sides of the head cover
New design is 2.2 lbs lighter than previous model
Weight savings and rigidity balance aided by down tube with a smaller cast bracket thats now formed via a swaging (squeezing and hammering) process
Swingarm pivot is located higher in the frame for improved rear wheel traction
Sub-frame is 1.3 pounds lighter via larger diameter tubing with thinner walls, yet still provides a secure mounting for the new silencer
New Aluminum SwingarmNew tapered D shaped cross section design is 5mm taller at the front (up from 74 to 79mm) and 2 mm shorter at the rear (down from 60 to 58mm)
Features a new cross bracket design
Provides a 0.9 lbs weight savings over the previous model
Alloy swingarm uses a cast front section, tapered hydroformed spars and forged chain adjusters
Uni-Trak® rear suspension system mounts the suspension arm below the swingarm, allowing a longer rear suspension stroke and more precise tuning
Design improves stability, rigidity and rear wheel traction
New Front ForkShowa twin-chamber fork keeps oil and air in separate chambers for stable damping performance during long motos
Super-hard titanium coating on the outer surface of the inner fork tubes reduces stiction and improves suspension action. The increased surface hardness of the dark navy blue coating also helps prevent scratches and damage to the tubes
Friction-reducing Kashima Coat on the inside of the outer fork tubes contributes to smoother suspension action, especially during the initial part of the stroke
Ideal rigidity balance via increased rigidity in the reshaped upper triple clamp and decreased rigidity of the outer fork tubes
Offset decreased from 24.5mm to 23.5mm, which combined with the frames revised rigidity balance and revised suspension settings, helps produce lighter handling
Enlarged, wrap around black fork tube guards provide greater protection for the inner tubes
Revised race-oriented suspension settings offer all-around performance improvement
New Rear ShockNew Showa rear shock features a revised layout and revised damping characteristics for improved performance
Better response and improved feeling, even when fully-bottomed
Features Kashima Coat on the tank cylinder for reduced friction and smoother suspension action
Rear shock features dual compression adjustability, allowing high-speed and low-speed damping to be tuned separately
Easier accessibility for tuning
New Skid PlateResin material offers greater protection without a weight increase
New Chain GuideMore slim and compact, down from 42.7 to 34mm wide, with 2mm thicker wear pad
Reduced weight and longer wear
Improved Rider Interface and StylingFoot peg width (front to rear) increased from 46mm on previous model to 50mm for improved feel
All-new body work and graphics
Right side panel has an added passageway to aid in cooling the silencer
Black plastic covers, triple clamps, number plates, and engine covers
Rims are coated in black alumite just like the factory racers
New seat design thats slimmer with firmer urethane for improved ergonomics and feel
Seat has a slip-resistant top surface for good grip when seated and smooth sides for excellent rider mobility
Monster Energy EditionSpecial Monster Energy graphics
All-new special black plastic bodywork and green hubs compliment Monster Energy graphics
Additional FeaturesLarger front brake lever boot offers increased protection against dust
Clutch cable boot features a large quick adjuster, for easy clutch cable play adjustment on the fly
Throttle grip has a one-piece collar that provides additional stability during throttle operation
Lightweight short-length grips feature a pattern designed to provide excellent grip
Rear caliper guard protects the caliper from damage
Ribless rear hub and butted spokes reduced unsprung weight
