New for 2009
- New White with Orange frame color joins White and Red on the TRX450ER.
- High-Performance Unicam® cylinder head design (see Technology Section)
- Compact, lightweight engine designed specifically for ATV usage is worthy of its CRF® heritage.
- Electric-start version features an electric starter that drives the clutch side of the crankshaft to provide superior lubrication of starter gears and to produce a narrow engine with a short, strong crankshaft.
- Lightweight, compact, internal auto decompressor provides superb cold-starting and hot-starting operation.
- Kickstart version incorporates ATV-type forward kickstarting for ease of starting and light weight.
- Crankshaft is made of high-strength, low-carbon steel with carburized main journals for maximum durability at sustained high-rpm operation.
- Cylinder-head cover is made of magnesium to reduce engine weight.
- Forged three-ring 12.0:1 compression slipper piston is lighter than a conventional design, revving quickly while maintaining excellent cylinder sealing and high-rpm power.
- Maximum engine rpm is 9850.

- Carburetor features a Throttle Position Sensor (TPS) that helps maintain linear response throughout the rpm range.
- Twin-sump lubrication system separates the oil supply for the crankshaft, piston and valve train from the clutch and transmission. This ensures a cool supply of oil to the clutch, eliminates clutch and transmission material contamination to the engine oil and reduces the amount of circulating oil and the required size of the oil pump.
- Vertically split crankcases feature a built-in oil pump, reducing weight compared to a conventional design.
- Left-side countershaft bearing and axle carrier feature double-row bearings for added durability.
