Good upgrade.

You're only going to make the standard forks better. I installed these with Hagon progressive springs & TEC Fork emulators and adaptors for Triumph 41mm forks. 2011 T100 much better now.

41mm pre load adjusters - used on Bonneville Speedmaster 1200

Easy to install - lift the front to unload the fork springs - they're ally so you'll need to protect them with decorators tape and use a single hex socket. I'm now in the tweaking stage searching for that "just right" setting for feel rather than setting sag. Currently set to 8mm extra preload with a 91Kg rider and front end seems much better. Using standard fork springs as Technical don't do progressives for the Speedmaster, only the Bobber.

Fork pre load adjuster’s

Easy to fit using standard springs and tube spacers , just trimmed it hem down by 5mm as suggested and they work a treat time will tell over longer journeys, when fitting do not over tighten and put some cloth or tissue under socket as not to mark the finish .
