Honda CRF450 gets pow­er­ful makeover

Motorcycle News (UK) - - This Week -

Honda have com­pletely re­worked the CRF450R and CRF450RX mod­els in what the firm says is a ‘ground-up redesign’ for their dirt bike range.

The mo­tocross CRF450R gets an 11% power boost at the top end along with stronger torque fig­ures across the rev range and there’s a new frame with a lower cen­tre of grav­ity and elec­tric start now avail­able as an op­tion.

The RX en­duro model gets a larger fuel tank, 18in rear wheel, side­stand, elec­tric start, re­vised sus­pen­sion and mod­i­fied en­gine map­ping more suited to the en­duro fo­cus of this bike.

Honda say changes to the CRF450R in­clude: “An 11% top-end power boost is pro­vided by a re­vised cylin­der head with greater valve lift, higher com­pres­sion ra­tio and new in­take giv­ing a straighter path­way into the in­let ports.

“Stronger torque, par­tic­u­larly low down, but right through­out the rpm range, gives a 5% im­prove­ment in ac­cel­er­a­tion out of the gate.

“New sev­enth gen­er­a­tion alu­minium frame with lower cen­tre of grav­ity, shorter wheel­base and shorter dis­tance be­tween swingarm pivot and rear wheel, of­fer­ing un­prece­dented lev­els of trac­tion, and a race-kit spec­i­fi­ca­tion 49mm Showa steel spring front fork, ti­ta­nium fuel tank, aero­dy­nam­i­cal­ly­ef­fi­cient plas­tics and the op­tion of elec­tric starter.”

Mikio Uchiyama, Project Leader for the CRF450R said: “Our fo­cus has been on pro­duc­ing a ma­chine with ex­cep­tional en­gine per­for­mance, out­stand­ing trac­tion and a low cen­tre of grav­ity.”
