For over 50 years, RK Takasago manufactures chains for motorcycles.
This is why manufacturers such as HONDA, SUZUKI, YAMAHA, KAWASAKI, KTM, DUCATI, TRIUMPH and MV AGUSTA rely in their original equipment on chains from RK .
The individual service and maintenance is essential for the life of the chain.
For details on the chain tension please refer to your driver's manual.
Chain lubrication should be applied to all 500 - 2.500 kilometers, which is ultimately pending
from the chain spray and the weather condition.
We recommend Chain Spray from PDL / Profi Dry Lube or the S100 products from Dr. Wack.
Never replace a component from the chain set (chain, front sprocket and rear sprocket),
if the wear has already been started. The involuntary chain elongation and the sprocket wear usually run parallel with identical qualities. The sprocket valleys
are broadened wider, the teeth become more pointed with increasing duration of use.
We recommend sprockets among others of JT-Jomthai, Maxum-Tech and Supersprox.
