2007 WR 450F - Pros & Cons

Strengths

Strong power output: With 58 hp @ 9000 rpm and 49 Nm @ 7000 rpm of torque on tap, the WR 450F is no slouch for its class.

Considerations

Tall seat height: At 998 mm, shorter riders will likely be on tiptoes at a standstill - worth sitting on one before you buy.
Modest fuel capacity: Range between stops is limited by the 8-litre tank - plan fuel stops accordingly on longer routes.
Chain final drive upkeep: Budget time for routine chain maintenance - it's cheap to replace but needs consistent attention to avoid premature sprocket wear.

Wear Points & Servicing Notes

Cooling system servicing

WR 450F's Liquid cooled setup is low-maintenance provided the coolant interval is kept - old, acidic coolant is the main cause of long-term corrosion in the water passages.

Brake disc and pad wear

Braking up front comes from Single 250mm disc 4 piston caliper - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The WR 450F's suspension runs 46mm Kayaba inverted telescopic fork, compression and rebound damping adjustable at the front. The rear uses Fully adjustable Kayaba single shock, 315mm wheel travel, separate speed compression adjustment. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The WR 450F uses chain final drive, which is cheap to replace but needs regular cleaning, lubrication and tension checks to get a full service life out of the sprockets.

Frame & chassis check

Built around a Steel, Single cradle frame, the WR 450F's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.

Low-speed handling

122 kg keeps the WR 450F easy to move around in tight spaces, car parks and on the stand alike.

WR 450F - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2007 Yamaha WR 450F, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy WR 450F should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a WR 450F's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.

Carburetor upkeep

Deposits in the carbs are the usual culprit behind poor running on a stored WR 450F - strip and clean the float bowls before the first start. Pilot jets clog first and get overlooked most, so make a point of checking them.
