IRC Quickshifters

IRC SGRace-2T Two-stroke Quickshifter

IRC SGRace-2T Two-stroke Quickshifter

Ref: 65067

Experience super-smooth, full throttle upshifting on the road and gain metres over your rivals on track!

Shift up through the gears at constant or full throttle - without the use of the clutch - for lightning smooth acceleration at any RPM.

Even though you may have an earlier two-stroke bike, there’s no reason why you shouldn’t benefit from today’s advanced electronics with the latest SGRace Two-stroke Quickshifter.

With its solid-state Load-cell/Strain-gauge Shift-rod Sensor - which, for absolute reliability, has no moving parts or switches to wear or fail - and, with the RPM Sensor cable connected, using same internal electronics as IRC also provide to leading GP teams, it will automatically adjust your engine kill time dependent upon revs to deliver the smoothest shifts all way up through the gearbox.

Supplied with combined installation guide and user manual, it's very straightforward to install on any single or twin-cylinder two-stroke with conventional CDI ignition and spade type terminal coils, requiring only external connections to: +12 V feed and earth, coil spade terminal(s), optional RPM Tacho (or HT lead) feed.

For ease of universal mechanical installation too, the Shift-rod Sensor has both left-hand and right-hand “magic” M6 threads with three M6 x 35mm male adaptor studs .

  • Upshift at full throttle without backing off and gain potentially 3 metres per shift or 2 seconds a lap
