New Bearings for your DRZ400.

If you are in the lower end doing work, new bearings are cheap insurance for all that hard work.

• Hot Rods complete stroker crank assembly includes +4mm stroke for maximum power and performance output.
• Hot Rods constructs their complete stroker crank assembly to meet or exceed OEM specifications for maximum durability.
• Hot Rods stroker cranks are completely rebuildable and have been trued to within 0.001" from the factory.
• The Hot Rods stroker crank increases the stock displacement to 424cc when used with the stock bore piston or 462cc when used with a 94mm big bore kit.
• Main bearings sold separately.

This will not fit the DRZ400 kick start models. Nothing is available for the kick start models.

This is a completely rebuildable stroker crank (3mm additional stroke) turns your mild mannered 250cc motor into a 263cc trail shredding monster! OK, maybe not, but sure makes it a fun machine.

Want the COMPLETE package? Order a Big-Bore kit to go with your stroker! That will give you a 308cc ripper! That is 24% larger than the stock 250. This package includes the Athena Big Bore Kit plus the 3mm Hot Rods Stroker Crank with new Genuine Yamaha crank bearings.

You will need to tune your EFI with something like the Power Commander V to get the most out of your Stroker kit.

For stock bore Hot Rods highly recommends you use the Vertex Stroker Piston Kit.

Billet plugs for your left side case. 

Includes both the timing mark plug and the crankshaft access plug.
