Believe it or not, it has been 15 years since the introduction of the first-generation CRF450R motocross bike. Not only has this bike been a huge success on the showroom floor, and in competition around the world, but the CRF450R also took home eight-consecutive Cycle World Ten Best trophies between 2002 and 2009, and remains one of the most winning models in the 40 years those awards have been handed out. For 2017, Honda has completely revamped the big CRF from top to bottom. Among the changes are an all-new Unicam engine with improved power and torque across the rev range. Significant changes to the cylinder head include the use of a finger rocker arm for increased valve lift, and oval-coil cross-section valve springs, the combination of which allows a lower engine height, plus makes the mill more compact and gives it a lower center of gravity. Additionally, the head has a narrower included valve angle (reduced from 21.5 to 19.5 degrees) for a straighter shot into the combustion chamber and improved burn from the mixture. Intake valves are now 2mm larger at 38mm. A new piston combined with a revised combustion chamber raises compression from 12.5 to 13.5:1, new four-hole oil jets for piston lubrication, and a new dual-stage scavenge pump reduce friction enough that oil volume has been reduced from 1,490 to 1,250cc; the lubrication system no longer uses two different oils and reservoirs for engine and gearbox. A new clutch, airbox, and exhaust system round out engine changes, while transmission ratios and final-drive gearing have been altered for the new spread of power.
