With leading edge technology and using only the highest grade of special steel alloys, JT produces a full range of superior quality motorcycle chains. JT advanced power transfer chains meet or exceed the requirements of all modern motorcycles, street, MX, enduro, off road and ATV. HDR/HDS is recommended only for off road. X1R has a recommended limit of both cc and bhp. Z3 can be used on any cc but because of the heavy duty construction, it should be used on 600cc plus applications (up to 1000cc for 520, up to 1400cc for 525 and 530). The bph is not limited but a guide line for maximum bhp should be set at 230 bhp which covers 100% of all models but excludes heavily modified engines for drag racing, nitro injection, etc..
