High Performance Race Bike Engine Builders 

Here at DART, we are meticulous about every engine build we undertake. Every aspect of the engine is measured, recorded and supplied as a reference for our customers for when the job is completed. We are fastidious about the quality of our engine builds and take great pride in their performance and reliability under the extreme race conditions our customers put them through.

Checking the deck height of the pistons at TDC is an essential part of the engine build process.
