Supersprox produces the best and the lightest aluminium sprockets in the world. Our sprockets are Original equipment on KTM, Husqvarna, Honda (HM) and others. If you have set your mind on light weight, then these are the best you could buy!

COLOURS:  Honda – Red / Kawasaki -Black / Suzuki – Black / Yamaha – Blue / KTM – Orange /Husqvarna – Red

We dont charge extra for colour, like some of our competitors. There is one quality and one high level finish, that we have chosen for all of our sprocket line.

Supersprox have developed several unique products over the past 45 years. We have also pioneered the way forward in technical design. Back in 2004, we introduced a special tooth design that increases chain contact and significantly extends the sprocket life – Its an exclusive feature!

Grooves between the teeth allow the dirt to be shifted from under the chain and this reduces chain load. All that dirt is abrasive and will prematurely damage your sprockets and chain. You really need grooves on aluminium sprockets, its not an option. So, we treat grooves as standard and dont charge for them
