Sorry haven't posted for quite some time..

Been concentrating on road cycling and indoor turbo trainer ''cycling'' during lockdown etc...Been away on holiday recently and decided to take my 2015 KTM Macina Force 29 MTB fitted with BOSCH Active Line motor . 600 miles in three weeks - It has about 4000 miles on it now and needs a new chain and front chain ring/sprocket.

Having nearly burst a blood vessel getting the KTM/Miranda lock ring / bash ring off....Must have been fitted by a silver back gorilla !! I know need a new chain and sprocket.

The original is an FSA WA648 15T which appears to have an offset on the rear .......They seem to be very scarce in the UK but wiggle have a BOSCH 15T sprocket listed as part number 1270016204. - is this ok ?

Also which chain do I replace with and can I use a quick link chain for ease of replacement next time ?

Advice needed before order placed - thanks in advance

it is real but a off set sprocket pushes it away from the motor more like a spacer for a better chain line.

with the one i linked to you have enough space to run 2 sprockets.
