JT SPROCKETS Counter Shaft Sprocket - 13-Tooth JTF1501.13

The counter shaft sprocket is the critical link between your engine's output and your bike's acceleration. A worn or undersized sprocket directly kills throttle response and top-end performance—upgrading to JT's 13-tooth design gives you the precision engagement and durability required for consistent power delivery, whether you're on the track or the street. JT's computer-optimized geometry ensures maximum strength without unnecessary weight, letting your engine work efficiently instead of fighting mechanical losses.

Built to motorcycle industry standards and beyond, this sprocket combines proven metallurgy with precision manufacturing. The heat-treated, bead-blasted construction reduces surface tension and extends service life, so you get reliable performance lap after lap without premature wear or failure.
