2023 Honda CRF450R Overview

The 2023 Honda CRF450R is a cross / motocross motorcycle built around 449.7 cc of displacement. Under the tank sits a Single cylinder, four-stroke engine running Single Overhead Cams (SOHC) valve actuation, a compression ratio of 13.5:1. The bore and stroke measures 96 x 62.1 mm. 2023 Honda CRF450R delivers 48 Nm @ 7000 rpm of torque. The factory-quoted top speed stands at 170 km/h, making it a capable performer in its class. From a practical standpoint, the 2023 CRF450R tips the scales at 111.1 kg, carries a 6.30-litre fuel tank, offers a seat height of 965 mm and spans a 1481 mm wheelbase. That's roughly 12.5 kg heavier than the average cross / motocross motorcycle in our database. Scroll down for the complete 2023 Honda CRF450R spec sheet covering every technical detail from suspension travel to tyre sizes.

2023 CRF450R - Pros & Cons

Strengths

  • Fuel injection: The fuel injection system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.

Considerations

  • Tall seat height: The 965 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.
  • Modest fuel capacity: The 6.30-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.
  • Chain final drive upkeep: Chain final drive needs regular cleaning, lubrication and tension checks to get full life out of the sprockets.

Wear Points & Servicing Notes

Fuelling & injector care

Fuelling comes from fuel injection. Systems like this are largely maintenance-free beyond keeping fuel quality decent and injectors clear - a fuel-system cleaner every service interval is cheap insurance.

Valve clearance checks

Single Overhead Cams (SOHC) valve actuation on the CRF450R means clearances should be checked at the manufacturer's specified interval - they can tighten as mileage accumulates, and a light top-end tick is usually the first sign.

Brake disc and pad wear

The Single disc. Hydraulic. Two-piston calipers. front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.

Suspension condition on used examples

Up front, the CRF450R runs 49mm inverted Showa fork with 13-position rebound and 15-position compression-damping adjustabilit and Pro-Link Showa single shock with adjustable spring preload, 11-position rebound and six-position high- and low-speed compression-damping adjustability at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.

Final drive maintenance

Final drive is by chain - expect to clean and lube it every few hundred kilometres and check tension regularly; a neglected chain wears the sprockets faster than the chain itself.

Frame & chassis check

The frame is Aluminium twin tube - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.

Low-speed handling

At just 111.1 kg, the CRF450R is light enough to manhandle easily at a standstill - one of the practical advantages of its class.

CRF450R - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2023 Honda CRF450R, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained CRF450R should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task on any CRF450R. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. The sump holds 1.80 litres, so budget for that volume of quality motorcycle-specific engine oil. Always use the correct viscosity grade as specified in the owner's manual.

Fuel system care

The CRF450R's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.

Valve clearance service

Check that valve clearances have been adjusted at the correct intervals on any used CRF450R. A bike with clearances out of spec doesn't always feel obviously wrong - but tight clearances accelerate valve seat wear. Ask for service documentation proving it's been done.
