Following last year’s major upgrades to the CRF450R, the CRF250R has now been given extensive improvements for even greater usability ahead of the 2013-14 season. 

A completely new mass-centralised chassis plus upgrades to the engine and suspension enhance rider control and feel, both on the ground and in the air. 

Internal improvements to the 48mm Showa inverted front fork are complemented by a compact new Showa rear shock, revised Pro-Link suspension and redesigned aluminium swingarm. The kerb weight is 105.7 kgs (233 lbs).

The flagship CRF450R, meanwhile, has received further engine development for greater torque, throttle feel, top-end power and over-rev. 

Delivering improved bottom-end torque, the CRF450R’s 449cm3 single-cylinder engine benefits from new Dual Fuel injection timing and updated twin rear silencers while the clutch features lighter springs - with no loss of durability. 

Its 48mm KYB air front fork has also been upgraded for improved oil flow and damping characteristics. 

The CRF450R can also be tied down for transport simply by removing air pressure, lowering the front end with no risk of damaging fork seals. The kerb weight is 111 kg (244.7 lbs) Honda released a teaser video of a nimble and revvy motocrosser, which could be the new 2014 CRF250R. More on May 14th.
