Race Ignition Kit Fits:


NOTE: We can aslo supply a system to fit the original CR72 race bike, this has no starter mechanism therefore a much shorter crankshaft.

  • Self generating (no battery required).
  • High performance cdi ignition system for twin cylinder 4 stroke with a 180 degree crank.
  • Low inertia rotor improves engine pick-up. Independent digital CDI (supplied with a user adjustable rev limiter 7000-13000rpm), and HTcoils for each cylinder, are programmed with an optimum advance curve specifically for this bike.
  • Maximum advance curve of this system is 35 degrees, so static timing is typically set to 10 degrees to give a total recommended advance of 45 degrees.
  • See fitting instructions for more information.
  • Manufactured in the UK.

In common with other suppliers we are unable to offer warranty for electrical components used for racing.
