This 7/8" handlebar diameter exhaust valve lifter is of the short curved lever type - and is is ideal for hooking one finger around, if you do not like the longer lever type.
I would imagine this is also useful on something like a trials bike, where you tend to use the exhaust lever to control the engine speed, descending hills and the like.
It is an offshore made product - but the chrome looks nice and quality is reasonable. As can be seen from the accompanyning photographs, we have also shown it alongside the two longer levered types we also sell, for comparison.
Sorry - only 7/8" handlebard diameter available - I am trying to source a manufacturer of 1" diamter variety though
