Chino, Calif. – January 14, 2010 – Yoshimura has been making high-end camshafts for more than 50 years and are now available for 2010 Suzuki RM-Z450 and Honda CRF150 and CRF250 motocross models. They started out designing superbike camshafts, but have since expanded the line of camshafts to include motocross motorcycles and ATVs. Yoshimura’s expertise and years of experience in building the best camshafts in the business is legendary. All Yoshimura camshafts are constructed from one-piece billet or blanks, not re-grind. As a result, our cams not only perform at the highest level possible, but they are also extremely durable.

Fujio Yoshimura supervises every aspect of the cam design and manufacturing process. The company’s investment in state of the art computerized equipment to aid in the design of Yoshimura cams pays dividends in performance. The results are spectacular. Yoshimura camshaft performance is known around the world as being of the highest level possible. They utilize a combination of computer, dyno, and real world, seat of the pants testing in addition to raw technology. In the end, Yoshimura cams are the ultimate statement in peak numbers and rideability. More importantly, this statement of applied technology lowers your lap times and helps you to win.

2010 Suzuki RM-Z250 ST-R Camshafts
With Yoshimura’s involvement in the Rockstar Makita Suzuki race team, the RM-Z250 receives a ton of Dyno time. The results are obvious. Tons of useable over rev let you hold the throttle on long enough to pass that guy in front of you instead of having to shift. Coming out of corners, the increase in mid-range is huge. These cams make the RM-Z250 pull like a tractor. This is a big increase in power and it’s all right where you need it!

09-10 Honda CRF 450R
Stage 1 Camshaft (Unicam)
The Yoshimura Camshaft Kit is the hot ticket for getting the most out of your 2009 Honda CRF450R. Yoshimura designed the CRF450R camshaft with increased lift and duration to produce a potent power curve with mid to top-end power & torque to accompany the power already available on the bottom end. This means when you whack open the throttle out of a corner, you’ll get a nice hit off the bottom and an even bigger kick on the top end. This Camshaft Kit is “drop in”, no shims or springs are needed.

Part Number: 2257-CS-KIT
MSRP $499.00

06-09 Honda CRF250R Camshaft (Unicam)

If you are looking for that extra edge then Yoshimura’s Cams for the CRF250R are just what you need. Way more snap, a healthy increase in mid range, and a screaming top-end are the reward. These benefits are not only felt on the start, but everywhere on the track. CRF250R Cams feature increased lift and duration over stock cams.

Part Number: 210-455-1052
MSRP: $625.00

07-09 Honda CRF150R Camshaft
Stage one for the CRF150R increases mid-range power on up into the top end. A ton more over-rev lets you hold it on longer without shifting too. Yoshimura cams provide more lift and duration to really let this little Honda rev.
