Honda CRF250R 2014

For HRC’s development engineers chosen revolution over and upgraded the CRF250R with the mass-centralised aluminium beam and design philosophy as the awesome The engine and PGM-FI fuel likewise have received to further improve power, and throttle control, while has been trimmed wherever

At the heart of the 2014 CRF250R’s is the aluminium beam frame debuted on the CRF450R for the 2013 year. The low centre of gravity and turning inertia the new chassis help improve the already handling abilities of the CRF250R ground and – perhaps even importantly – in the air. Internal to the 48mm Showa inverted fork are complemented by a compact new rear shock, revised suspension and redesigned aluminium

Always a jewel of usability, incredible drive from in its wide rev-range, the 249cc has received a multitude of upgrades HRC’s development engineers major work on the PGM-FI injection, gas flow through the as well as intake and exhaust

The new CRF250R has been honed to an higher state of perfection once again, HRC has created a in a state of the purest balance, the riding tool for the professional and alike.


HRC started out a number of requirements for their generation of aluminium beam improved front and rear – plus the feel for available so important to a rider – high-speed and braking plus a much sensation when turning in all and conditions. In every respect the new frame is a game changer in its

It’s a complete redesign. in at just 9.35kg, the junction of the head and main frame now intersect much lower on the head pipe, closer to the point rather than the top. This change lower the centre of gravity and more ‘tuned’ flex the chassis for better front-end and improved corner speed.

The steering geometry of 27.23°, 116.7mm trail and wheelbase of takes advantage of the frame’s performance parameters and gives a direct connection to the front with increased feel for traction and faster turn-in. with the lower centre of side-to-side transition is easier, increasing rider confidence and fatigue.

A CRF250R-exclusive lower houses the engine. Careful of equipment around the frame to mass centralisation, the subsequent in inertia and lighter overall of the CRF250R. The electrical components – condenser, regulator and wiring – save weight and are centrally below the throttle body.

lighter weight radiators – to the CRF250R – are mounted lower.

The top mount of the Showa rear is sited 14.5mm lower the frame and the shock itself is 14.5mm smaller, and features a spring weight plus new and compression damping rates. The of mass centralisation in this is reduced pitching inertia the bike’s centre line; braking is possible with stability. The new aluminum swingarm added rigidity thanks to beam height in the front and sections, minimising deflection and rear tyre traction on exit.

The Showa 48mm cartridge forks received new sub-piston diameter in the 2013 year – from 35mm to – with improved low speed For 2014 the spring weight has updated to suit with the new Rebound and compression damping adjustable through 16 positions.

The rear suspension features new linkage ratios and allows of wheel travel. Fully the rear shock features rebound adjustment; compression is separated into 13-position and 3.5 turns (high speed).

The CRF250R’s new bodywork inherits an of the ‘triangle proportion’ dynamic on the 2013 CRF450R; the motorcycle is built about the rider’s with mass centralisation and ergonomics key. The radiator side covers, lightweight and fuel tank offer a smooth and continuous transition the rider huge freedom and of movement.

Also, the bodywork points – where the rider the bike – are extremely rigid so the can grip the bike hard for feel and control. In addition, the fender has a lift point integrated support to make it to hoist the bike onto a

Lightweight 80/100-21 front and rear tyres save weight. Protecting the front wave pattern disc and brake caliper is a two-piece the rear 240mm wave-pattern and single-piston caliper is also

During this of development HRC’s race focused attention on a number of to further improve the CRF250R output and delivery. The 249cc, four-valve Unicam unit has impressed with its broad of useable power no matter the plus a crisp and instant response. Building on this drivability and searing top-end the targets.

Combustion efficiency, to a higher compression piston ratio is increased from to 13.5:1) and re-shaped cylinder and inlet/exhaust porting, is improved. and … remains 76.8mm x the 30.5mm diameter titanium valves and 25mm dia. exhaust valves are also The 5-speed gearbox has been to improve durability.

Power and improvements have been on the all-important low-to-mid range.

Like the 2014 CRF450R, the capacity sibling gains new mapping with Dual timing and employs a revised angle. A CRF450R specification is married to a dedicated CRF250R air and twin rear mufflers – mass once again – are to the CRF250R.
