Cylinder attaches to engines cases with through-bolts instead of studs, allowing in frame cylinder removal. Handlebar holders provide two different mounting positions to match rider preference. Front disc brake cover helps protect rotor and caliper from damage. The 2009 CRF450R has vaulted so far ahead that it redefines expectations in the premium class of motocrossers. Engine height reduced by shortening length of connecting rod 3.5mm (105.6 to 102.1mm) to allow shorter cylinder. Damping action smoothly progresses as handlebar deflection increases, which produces very natural steering characteristics and feel. By reading the previous you would ask yourself what improvements were made to the bike and the answer comes naturally. Wide, cleated stainless steel footpegs are self-cleaning and corrosion resistant, provide excellent grip and fold for extra ground clearance. During the process of building the all-new frame into a complete rolling chassis, all options for attendant suspension components were considered. Javascript must be enabled for the correct page display, liquid-cooled single-cylinder four-stroke. Im guessing i got around 120km/h.

Clutch cover profile reshaped for improved foot placement. As we already mentioned, the engine comes in pair with a 3-speed automatic transmission. New forged slipper-piston material permits thinner crown, contributing to shorter cylinder height. Large 50mm rear shock damper piston diameter for consistent performance under demanding riding conditions. Shaving a small flat into the bottom of the crankshaft flywheels allowed for a bit more con-rod shrinkage by providing a pinch of added clearance for the piston skirt, while also reducing weight—an insightful bit of efficiency contributing to the shorter engine. Transmission ratios remain the same as last year, and the transmission still incorporates a gear-position sensor, which now also works in conjunction with the EFI system. Removable rear subframe was redesigned to eliminate brackets and cross-members. Anti-vibration damping is a game changer. In 2003, the engine received many improvements like the cam timing and lift changed for stronger low-end power and torque output, and smoother idling. Lightweight Nikasil cylinder lining provides cooler and quieter operation for extended engine life. Fuel Capacity: 1.5 gallons Yet from that side, the 2009 CRF450R offers a great look of its new waved rotors that are seriously protected from mud. Since its introduction, the CRF450R has enjoyed a well-deserved reputation as being the easiest starting bike in its class, as well as having the best throttle response. I was happy to be riding the new CRF because all the information was more than positive: the silky power delivery was so sweet that it makes you wonder if the single cylinder makes any bangs. Also, the removable rear subframe features an unusual, almost oval tube shape; flatter on the sides of the tubes to further narrow the bike’s profile for superior riding ergonomics, and also shaped to eliminate brackets and cross-members and facilitate improved air-filter access. The result is the world’s only mass-produced, fuel-injected motocross bike, designed to compete with Honda’s class-leader, the CRF450R. Thanks to the steadying influence of HPSD, more aggressive steering geometry could be engineered into the CRF450R, which is reflected by the 20mm of offset in the 2009 triple clamps, for improved cornering agility without giving up anything in high-speed handling. Trail: 111.4mm (4.3 inches) A new rear axle features a diameter of25mm and large-diameter bearings provide additional rigidity. Lightweight titanium intake valves permit use of smaller valve springs and reduce overall engine height. The plastic fuel tank has been strengthened to ensure proper sealing for the lightweight plastic fuel pump, which resides within the tank. This ensures a cool supply of oil to the clutch, eliminates clutch and transmission material contamination of the engine oil and reduces the amount circulating oil and minimizes oil pump size. I sure don’t think so! All of which points to a machine that’s as versatile as it is victorious. What hit me first on the 2008 CRF450R was the ergonomics. Top speed at the drag strip= 163 mph!! supporting the double-taper aluminum swingarm tuned for maximum strength and minimal weight. The overall weight was reduced by 1.5kg and that was mostly due to the new piston shape for increased torque over entire rev change, new exhaust system layout which optimizes mass centralization, and the new standard equipment Renthal bars (971 Bend). Narrower engine allows right-side engine guard to be eliminated, saving weight. So even though it was no small task to improve on the best carburetion system around, thanks to countless hours of testing and perfecting this system the new CRF450R meters fuel even more precisely now. of torque at 6500 rpm. 2021 CRF250F OVERVIEW - Honda There are plenty of ways to enjoy the great outdoors, but a dirt bike is one of the best.
