I need to change the chain and sprockets on my 2015 Triumph t100 EFI 865. Having looked on line I have realised there are different size rear sprockets and chains depending on the year and model. I think my bike has a 43 tooth sprocket and 525 chain with 104 links but I am not sure. I am also going to use a 19 tooth drive sprocket. Thanks David
The sprocket size should be in the owners manual, probably in the specs near the back under final drive. Could be stamped on the sprocket too! Failing that, just count the teeth.
