§ 02 / About this part
What it is
The VERTEX ENGINE BOTTOM END YAMAHA REBUILD KIT, engine. Stocked by Iron Offroad, the UK MX hard parts specialist.
Refresh the rotating assembly with this kit. It addresses the crankshaft, main bearings, and seals deep inside the cases. Bottom-end wear usually manifests as excessive big-end play or oil seal failure. These components are vital for maintaining structural integrity and smooth power delivery. Each kit includes a crankshaft, main bearings, and a gasket set for splitting and resealing the cases. Fitment is model-specific to ensure correct oil-way alignment and crank balance. Ensure your cases are clean and mating surfaces are flat before installation. It restores your bike to factory tolerances for demanding race or trail use.
