If you're looking to unlock the true potential of your motorcycle, you're in the right place. At JR Motorcycles, we specialise in custom ECU remapping and Dynojet tuning to help riders get more out of every ride — more power, smoother throttle response, and improved overall rideability.
Why ECU Remapping?
Most motorcycles come with a factory ECU (Engine Control Unit) map that’s built to meet global emissions standards and average fuel qualities. While that makes sense for mass production, it doesn’t mean your bike is performing at its best for New Zealand roads — or for your riding style.
That’s where we come in.
🔧 Our Performance Tuning Services
✅ Custom ECU Remapping
We rewrite your bike’s ECU to deliver optimal air/fuel ratios, adjust ignition timing, and improve throttle response. Whether you ride a touring bike, adventure machine, or a weekend rocket, we fine-tune it for your specific goals — power, efficiency, or smoothness.
✅ Dynojet Tuning
With our in-house Dynojet dyno, we can precisely measure your bike’s performance and make data-driven adjustments. See real gains in horsepower and torque — not just promises.
✅ Bricked ECU Recovery
Accidentally bricked your ECU with a bad flash or failed tune? We offer ECU recovery services to bring it back to life safely and quickly.
✅ Derestriction Services
Is your bike held back by manufacturer-imposed restrictions? We can derestrict your ECU where legally permitted, giving you access to the power your engine was truly designed for.
