Camshafts are the heart of any engine and is where tuning started for us. In 1954 Pop Yoshimura was grinding cams by hand. A lot of time has passed since then, one thing has not...passion. Today, Yoshimura cams are created in Japan from a special steel alloy billet and is just what the CP2 engine needs to make more grunt.

  • Full billet intake and exhaust cam, made by Yoshimura Japan
  • Full billet construction offers increase durability and quality over OEM or regrind options
  • Intake lift 9.70mm / duration 252 degrees
  • Exhaust lift 8.40mm / duration 248 degrees
  • Includes matching set of valve springs

  • Requires aftermarket pistons for increased valve lift

Kevin ★★★★★

Installation was pretty straightforward, but the real magic happens once you get it on the dyno. The mid-range pull feels completely transformed compared to the stock grind, and the bike just wants to keep climbing to redline. Worth every penny if you're chasing lap times.

Grace A. ★★★★★

The low-end torque gain is exactly what my R7 needed for tighter canyon runs, and the idle is surprisingly smooth for a race cam. Pulls hard all the way to redline without any fuss.

Ella ★★★★★

Installation was straightforward and the lift at higher RPMs is exactly what I was hoping for. The precision machining on these cams is obvious once you have them in hand. Really woke up the mid-range on my bike.
