VOL. 54 ISSUE 30 AUGUST 1, 2017 P51 Electric starting is standard. L ike the Honda CRF450R last year, the 2018 CRF250R gets a ground-up overhaul. Some of the most notable changes start with the engine. Honda has abandoned its former Unicam valvetrain for a dual-overhead-cam configura- tion with larger valves, and a finger rocker arm with Diamond Like Coating (DLC), all designed to give the engine more high- rpm power. It also has a new piston, twin exhaust ports, higher compression ratio, and a more oversquare bore and stroke ar- rangement. Just about everything in the engine, including the clutch and transmission, has been changed to either increase reliability or power, especially at high rpm. In a somewhat surprising move, the new CRF250R gets electric starting, just like its bigger brother. Providing juice is a high-tech, super lightweight lithium-ion phosphate battery, just like the ones the factory race bikes use. Chassis is all-new, too. It has a new and lighter (by about a pound) frame, shorter wheelbase, a lower center of gravity, a new swingarm, a lighter subframe and coil-spring forks (bye- bye air forks). Underneath the plastic top cover is a titanium gas tank. Claimed curb weight is up about seven pounds, mainly be- cause of the electric starting and going back to spring forks. MSRP has yet been announced, nor has availability. CN 2018 HONDA CRF250R
