This GSX-R750 came in with a non-working quickshifter (easily fixed, it was a blown fuse) and for a slipper clutch as the owner does a lot of trackdays and wanted to update his bike’s performance a little. We’ve seen this a lot over the last 12 months – many people are staying with the bike they have, and upgrading it rather than chopping it in for a new model.
The Sigma clutch went in fine and is good for trackday use. For racing purposes, however, we’d recommend an STM unit, from long experience of the way they work and durability.
Many riders are updating the bike they have with new bits, rather than buying a new bike; this GSX-R has now got a slipper clutch.
