ProTaper – ProTaper Rear Sprockets - Honda - 49-52 Tooth, including 49, 50, 51 and 52 tooth aluminum rear sprockets in black, red and blue, plus shared Honda/Yamaha 49 tooth options, pushes gearing shorter, and that changes the character of a CRF immediately. Adding teeth at the rear multiplies torque at the wheel, so a 51 or 52 tooth setup drives harder out of tight ruts, climbs steep faces with less clutch, and makes a 250 feel far more willing in slow, technical terrain. Riders who race supercross-style tracks, arenacross layouts or tight woods often start here rather than fighting a bike geared for open ground. The 49 and 50 tooth choices sit between stock and aggressive, which is useful when you only need a small correction after a front sprocket change. All sizes are cut from hard-anodized aluminum for low rotating weight, with tooth profiles machined to seat chain rollers fully and resist hooking. Colored anodizing in red, blue and black keeps the finish looking sharp through wash cycles. Choosing the right ProTaper tooth count sharpens acceleration, reduces clutch abuse, and gives you drive exactly where the track demands it.
