The Honda VFR (NC30) and RVF 400's (NC35) were amongst the top 400's in the '80's and 90's .. and if properly maintained their good handling and light weight means they are still fast now.
Bikes of that time missed out on the benefits of slipper clutches however and we can now bring the undoubted benefits of a good slipper clutch to the party.
The clutch uses supplied springs and the supplied clutch pack. The clutch provides all the normal slipper clutch benefits with better over-rev protection and improved chassis stability going into corners.
