This prevents overcooling.\n\u003cbr\u003eThe thermostat unit is sold separately.\n\u003cbr\u003eA highly reliable cartridge-type paper oil element is used.\n\u003cbr\u003eDurable glass is used for the engine oil check window.\n\u003cbr\u003eAn integrated clutch cable receiver is adopted.\n\u003cbr\u003e●Slipper Clutch\n\u003cbr\u003eThe slipper clutch slips the clutch when sudden engine braking (back torque) occurs, controlling the effectiveness of the engine braking.\n\u003cbr\u003eThis reduces sudden changes in posture due to engine braking, hopping of the rear tire, and stress on the engine.\n\u003cbr\u003eOf course, during normal driving, it operates the same as a conventional special clutch, so the clutch will not slip even with a high-power engine.\n\u003cbr\u003e●Slipper Clutch Structure\n\u003cbr\u003eA dedicated pressure plate and clutch cam are provided in the clutch section that connects the power between the crankshaft and the transmission.\n\u003cbr\u003eThis allows back torque transmitted from the rear wheel to be transmitted to the clutch cam, activating the cam of the pressure plate and the clutch cam, pushing down the pressure plate to create a semi-clutch state, and releasing the back torque.\n\u003cbr\u003e●Slipper Clutch Specifications\n\u003cbr\u003eSimilar to the standard clutch, a secondary clutch attached to the main shaft of the transmission is used to reduce the load on the crankshaft.\n\u003cbr\u003eIt also allows for a lighter crankshaft axis, resulting in brisk throttle response.\n\u003cbr\u003eA damper is incorporated into the primary driven gear to reduce shock when the clutch engages.\n\u003cbr\u003eIt has 5 friction discs and is compatible with high-power engines for both street and race use.\n\u003cbr\u003eA machined aluminum lifter plate is used.\u003c\/p\u003e\n\n\u003cp\u003e■Compatible Models\n\u003cbr\u003eHONDA\n\u003cbr\u003eCRF50F (AE03-1400001～)\n\u003cbr\u003eXR50R (AE03-1000001～)\n\u003cbr\u003eCRF70F (DE02-1700001～)\n\u003cbr\u003eXR70R (DE02-1300001～)\n\u003cbr\u003e*Not compatible with XR70R Frame NO: DE02-1299999 or earlier, as parts are different.\n\u003cbr\u003e*Models with white fuel tank and front\/rear fenders.\u003c\/p\u003e\n\n\u003cp\u003e■Notes\n\u003cbr\u003e*Images are for illustration purposes only.
