Here is the complete lower engine pack proposed by HOT RODS for your YAMAHA YZF 250cc 4 stroke from 2003 to 2013.

This pack includes a complete engine gasket kit (except head cover gasket), C3 reinforced bearings and a forged crankshaft HOT RODS as well as these spy seals (compare to the pack proposed at BIHR). It will allow you to start again on a solid and quality basis so that you don't have to dismantle your engine often.

The paper gasket, O-ring and spy pack are from the brand VERTEX. The kit is complete except that the head cover gasket is not delivered with it. This is not a big deal, because even if you disassemble your head cover this gasket is one of the only ones that can be reused.

The crankshaft is forged from the best steels on the market. It is adjusted and balanced to guarantee a better reliability in all conditions.

The connecting rod is equipped with a treated crank pin and a reinforced silver needle cage. You can therefore mount this reinforced crankshaft on the original engine, but also on a big bore kit for example.

The bearings are identical to the original. They are manufactured in the same standard of quality to ensure optimum reliability on your machine.
