We replicate the dimensions of manufacturer’s original parts and this often results in bolts with a low head profile, therefore a small and shallow drive. Torque Guide for Fasteners in General UsageFor both Titanium & Stainless Steel where possible use the same torque as manufacturer’s originals. The force acting in the lubricated bolt can be calculated as, Flubricated = (2022 Nm) / (0.2 (0.03 m) (1 - (40%) / (100%))). Google use cookies for serving our ads and handling visitor statistics. If used in conjunction with a steering damper, it is essential to check that the steering is not affected. Before you start work on your machine ensure the bike is secure, positioned on a paddock stand where necessary. After fitting new parts we recommend you take your motorcycle for a short test ride, riding with care. The proof load for a M30 metric bolt grad 8.8 is 337000 N.

Lubricate all contact areas of the bolts and washers. You are entirely responsible for ensuring any bolts are correctly fitted and ProBolt Fasteners Limited shall not be liable for any damage or harm that is as a result of you having fitted the bolt without having sought such advice or for any incorrectly fitted bolt. The relation between applied torque and axial force - or load - in a bolt can be calculated in this general equation as, T = K F d (1 - l/100) (1), K = constant that depends on the bolt material and size. For mixed metals, use the torque of the lower of the two metals Torque range is normally calculated +/- 10%.
Use manufacturer’s original seals in conjunction with seal supplied by Pro-Bolt. Our accessories are matched to specific bike models by premeasuring those bikes – however, it is possible that manufacturers apply changes mid model without our knowledge, and we therefore require that you exercise due care prior to fitting.
