very small don't know if will work on Harley's
No mention of dimensions given when purchased but similar to the JMS part from US. Looks small but, assuming it will do the job intended for. It feels solid and hard enough to cope with the forces it will take when locked in position. Thank you.
If you read the HD manual, it states ‘Do Not’ use this form of wedge to hold the primary chain from moving but, a flat metal bar of certain length.
