Engine Fastener Kit BOLT — Ref. E-YF4-1420

Designed for the maintenance and restoration of engine fasteners on off-road machines, this BOLT fastener kit meets the needs of motocross and enduro riders. BOLT offers tailored solutions for most off-road motorcycles from 1985 onwards, allowing for the replacement of worn or corroded fasteners and ensuring a secure engine fit within the frame.

Regularly replacing engine fasteners is an essential maintenance task after muddy rides or intense seasons: loose screws, damaged threads, or oxidized parts can compromise mechanical integrity. This kit is aimed at both DIY enthusiasts and workshop mechanics who want to refurbish the mounting points of the engine block and minimize the risk of loosening due to vibrations.

Compatible with, among others:

• YAMAHA WR 450 F (2023 - 450 cm³)
• YAMAHA YZ 450 F (2022 - 450 cm³)
• YAMAHA YZ 450 F (CJ23) (2021 - 450 cm³)

Usage tip: adhere to the torque specifications recommended by the manufacturer and check the condition of the threads during installation to ensure reliable engine fastening before getting back on the track.
