Value upgrade with positive results.

Fitted the rear shocks at the same time as the progressive front springs.
I'm always cautious not to convince myself that work done sees an improvement but I my honest opinion this excellent bike is now even more enjoyable to ride.
A lot more comfortable over a wide selection of our 'most excellent' British potholes err roads.
Easy installation. Take heed of the install videos and you can't go wrong.
Thank you TEC.

Bike it should have been

Bought my Speed Twin early this year,
great bike but surprisingly for the brand, overly soft and under damped suspension. Watching many reviews, Tec kept getting mentioned. Very helpful,sorted postage to the Isle of Man, prompt delivery of front and rear suspension, great price and easy fit. Much improved ride solo and two up. I would highly recommend these products to transform the handling of the bike👍
