Bonneville forks upgrade

Bought new springs, valves and adjusters for my T100 as the original front suspension is rubbish. Haven't had time to fit them yet but the parts look to be really good quality and the backup and service from TEC was first class as always.

New fork internals

Purchased the progressive springs and preloaded adjusters, clear instructions with kit, also watched online video, easy job for anybody with mechanical experience, the new internals smooth out the ride and improve sterring when set up, I'm running with just a little preloaded, worth the small investment, waiting now for rear shocks to come in stock 5*

Pre load adjusters for 2018 T100

Fitted the pre load adjusters at the same time as the progressive springs. A few small burrs on a couple of threads had to be attended to before fitting but otherwise good quality. Care is required when tightening in fork legs. I used masking tape on open ended spanner jaws to prevent damage. Being black you hardly notice the adjusters once handlebars are back in place. So far I’ve found that little pre load is actually needed as the new springs seem to make the firmness of the ride just about right for me and are huge improvement over the original springs (see my separate review of the springs). I ride solo without luggage.
I’ve made several purchases from Tec and their service is great and products good quality considering the reasonable prices.

Pre loaders

Great product... high quality.. very easy to fit.

Allows adjustments to the fork spring load to tune it to the road surface encountered. The roads where I live go from race track quality to very poor all within a 10
mile ride, so setting up the suspension is always going to be a compromise.

This kit gives you that little extra to greatly improve set up.

Highly recommended.
