2017 Honda CRF150R Torque Specs
Shop parts for a 2017 Honda CRF150R Dirt Bike.
The 2017 Honda CRF150R continued as the gold standard for small-bore four-stroke motocross competition, combining its 149cc liquid-cooled DOHC engine, aluminum twin-spar frame, and fully adjustable Showa suspension into a package that consistently challenged at the front of the 150 and supermini classes. For service work on the 2017 model, these torque specifications apply to every fastener from engine internals to brake hardware.
Head Bolt Torque & Gasket Sealing
The 2017 CRF150R's liquid-cooled engine has more sealing surfaces than an air-cooled mill. Head bolt torque applied in a cross-sequence prevents uneven gasket compression that can lead to coolant intrusion or combustion leaks at the head joint.
