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!

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.

These benefits are not only felt on the start, but everywhere on the track. CRF250R Cams feature increased lift and duration over stock cams.
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.
