I need to purchase a chain/sprocket kit for my son's 2003 KX-100. The stock gearing is; front-15T, rear-49T, 420x124 links.
The previous owner installed a 428 non O-ring chain. Assuming the 428 links are slightly longer, wouldn't I need less links? I Want to install an O-ring chain this time around for ease of maintenence.
Does anyone know how many links I should order for the 428 O-ring chain with the stock gearing?
