2009 Honda TRX450ER (Electric Start)
The Honda TRX450R stands tall as one of the hottest, most dominant sport ATVs ever built. Check out its nearly endless tally of race wins and championships, including three (and counting) Baja 1000 titles. The TRX450R's secret: a superb balance of power, handling and reliability. To top it off, the TRX450R gives you the added versatility of electric start, to make sure you keep going strong.
Sure, the Honda TRX450R makes huge horsepower. But it also handles with a confidence-inspiring predictability that lets you have fun with that power. Its 449 cc four-valve Unicam engine comes from the awesome CRF450X race bike, but it has been carefully adapted for ATV use with a special piston and camshaft and a heavy-duty clutch. To make sure you can put all that power to good use, the TRX450R boasts a lightweight chassis with a racy cast-aluminum swingarm, double-wishbone front suspension with fully adjustable Showa shocks, and powerful, predictable disc brakes front and rear.
Available in manual- and electric-start versions, the mighty TRX450R has won races in virtually every ATV racing arena as well as four victories in the grueling Baja 1000.
Features & Benefits
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.

- 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.
- Exhaust system uses a lightweight, stainless steel header and muffler.
