Big difference

Used with new springs from TEC. Brilliant device at a very reasonable rice. Well made and had no problems fitting at all.

David Abrahams
Very useful to get pre-load just right.

Fitted to my 2017 Triumph Street Twin at the same time as fork emulators. Now able to tweak the pre-load easily which has allowed me to get rid of the tendency of the bike to fall into slow corners.

Fork preload adjusters

Appear to be very nicely machined and finished
Easy fit. I lined my open ended spanner with masking tape to guard against damaging the finish
