On the road, the 2007 CRF450R tips the scales at 99.1 kg, carries a 7.19-litre fuel tank, offers a seat height of 955 mm and spans a 1,491 mm wheelbase. The full 2007 Honda CRF450R spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2007 Honda CRF450R compared with other bikes in the Cross / motocross category

We checked the recorded figures for the 2007 Honda CRF450R against up to 224 bikes in the Cross / motocross category in our database, counting each model once at the model year nearest to this one.

  • Only 45 of the other 223 bikes in the Cross / motocross category have a larger engine displacement than the 449 cc of the CRF450R.
  • With 955 mm, the CRF450R has the joint 59th tallest seat height of 200 bikes in the Cross / motocross category, 6% above the category average of 899 mm.
  • Narrowing the field to the 110 models within five model years of it, the engine displacement of 449 cc is larger than that of 80 of the other 109.

Versus the 2006 model

The figures we track are unchanged from the 2006 model: displacement and seat height all match.

2007 CRF450R - Pros & Cons

Strengths

  • Strong front braking: Stopping power up front is strong thanks to the single disc setup, with plenty of room to upgrade further with braided lines.

Considerations

  • Carburetor fuelling: Expect to spend more time keeping the carbs in tune, especially after long storage periods or a change in altitude.
  • Tall seat height: At 955 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 7.19-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

Carburetor maintenance

Carburetors on the CRF450R need periodic attention - pilot jets and float needles are the first parts to gum up after the bike sits, and the first thing to check if idle or throttle response degrades.

Brake disc and pad wear

Braking up front comes from single disc - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The CRF450R's suspension runs 47mm inverted Showa cartridge fork with 16-position rebound- and 16-position compression-damping adjustability at the front. The rear uses Pro-Link Showa single shock with spring-preload, 17-position rebound-damping adjustability, and compression-damping adjustment separated into low speed. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The CRF450R 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.

Low-speed handling

99.1 kg keeps the CRF450R easy to move around in tight spaces, car parks and on the stand alike.

CRF450R - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2007 Honda CRF450R with its 449 cc cross / motocross, cover the fundamentals: service book and oil change history, drivetrain wear, and any sign of oil weeping around the casings. This model runs chain final drive, so check chain slack and sprocket tooth profile specifically - a worn sprocket is a cheaper fix now than after it's chewed up the next chain. Now 19 years old, this cross / motocross is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Cold-starting it yourself tells you a lot - a healthy CRF450R should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects the CRF450R's 449 cc single cylinder like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). With a 12.0:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. 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 CRF450R - 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.
