Bikes, quads and side-by-sides mapped with the same in-house care as the cars — fuelling, throttle response, limiters and sound, for road, green lane and track.

Why bikes respond so well
A bike or quad feels every change immediately — there is no two tonnes of bodyshell to hide behind. Cleaning up fuelling, softening a snatchy throttle map or correcting a market-imposed restriction transforms how the machine rides far more obviously than the same work on a car.
The usual requests are: smoother low-throttle response for slow technical work, corrected fuelling after an exhaust or filter change, restriction and limiter adjustment for track machines, and a little noise on the overrun for the ones that live at events.
Everything is written for your exact machine and its modifications, with the original calibration saved first — the same process as the cars, on a smaller engine.

The result
What riders ask for
Correct fuelling
After a pipe or filter, the factory map is no longer the right map.
Track restrictions
Machines set up for their class rather than for a showroom.
Sound on overrun
For track and event machines — calibrated, not crude.

Good to know
Questions we hear every week.
Which bikes and quads can you map?
Most modern fuel-injected machines. Tell us the model and year and we will confirm before you book.
I have fitted an exhaust — do I need a remap?
Almost always, if you want the benefit. The factory map was written for the factory pipe; after a change the fuelling is no longer optimal.
Can you undo it?
Yes. The original calibration is saved before we write anything.
Two wheels or four — same care.
