2007 CRF150
The 4-stroke motocross revolution continues with the introduction of the totally new CRF150R. This highly charged dirt track racing machine is destined to transform motocross racing’s smallest-displacement class with all the exciting performance and handling attributes that have proven so effective in Honda's big-bike ranks. Following the trend begun by the CRF450R and continued with the CRF250R, Honda's new CRF150R and big-wheeled CRF150R2 are set to shake up the small-displacement classes of 2-stroke MX machines.
Powered by a scaled-down and updated version of Honda’s race-proven CRF Unicam 4-valve engines, the new CRF150R is staged to grab the holeshot in its class and power its way to the winners’ podium throughout the racing season. With its compactly proportioned steel tube frame, inverted cartridge-type front fork and aluminium Pro-Link swingarm, and aggressively designed bodywork, the newest little CRF gives aspiring young riders everything they need to grow into racing experts, battle the competition and go for the gold.
