2000-2013 Suzuki DRZ400 Wide Ratio Gearbox

Full wide ratio gearset for the Suzuki DRZ400 with 3 undercut dogs per gear for fast accurate gear changes and positive retention. These gears fit the S, E and SM models from 2000 to 2013.

We supply the loose gears (2nd-5th Input & 1st-5th Output). These should be assmbled onto the standard input & output shafts using genuine Suzuki circlips, washers, bushes, etc.

We can supply the genuine Suzuki parts needed for assembly and/or assemble the shafts at additional cost. Please contact us for a quote.

NOTE: A small amount of material needs to be removed from the inside of the crankcases and two of the selector forks to provide clearance for the new larger diameter gears. A modification guide can be found by clicking here
