Quad and UTV crankshafts - the key to reliable engine operation

The crankshaft for a quad bike is the most important element of the crank-piston system, which converts the movement of the piston into rotation and transmits power to the gearbox. Its technical condition determines the working culture, efficiency and durability of the engine. At Bajamoto you will find crankshafts for quads and UTVs from the brands Hot Rods, ProX, Athena, Wossner, Vertex and All Balls - ready to install and perfectly balanced.

Why is replacing the crankshaft so important?

The crankshaft in an ATV engine works under enormous overloads, often in mud and at high temperatures. Over time, the journal may wear out, bearings may become dislodged or unbalanced, which causes vibrations and faster wear of other components. Therefore, it is best to replace the shaft together with connecting rod and crankshaft bearings.

How to recognize a worn crankshaft in a quad?
