Power derestriction
Unlocking French-market and US-market versions, speed limiters, power in the lower gears and the restriction fitted for A2.
What we unlock
- French-market and US-market versions (FR/US),
- speed limiters,
- power limits in the lower gears,
- the A2 power restriction.
Examples from the archive
Three results with numbers:
- Yamaha FZ1 FR: 106 → 150 HP (at the crank),
- Honda CB1000R: 106 → 125 HP (at the crank),
- Kawasaki GTR1400 FR: 86 → 122 HP (at the rear wheel).
For each result we state where the power was measured. Crank and wheel are two different measurements, so without that information the figures cannot be compared.
Also from the archive:
- Honda VFR1200F DCT: speed limiter and power limit in the first three gears,
- Yamaha FJR1300 FR,
- Yamaha MT-09: limiter.
More results: dyno results.
Important: documents
Derestriction changes the motorcycle's parameters, so remember that it must remain consistent with the vehicle documents. The data in the documents should match the condition of the motorcycle.
Once the A2 restriction is removed, riding such a motorcycle requires a category A licence, not just consistency with the vehicle documents.
How to get started
Give us the make, model and year, and tell us what the motorcycle has now: a French-market or US-market version, a limiter or an A2 restriction. Write to us or call.
Looking for the opposite direction, that is power restriction for A2? See A2 power restriction.
What the price depends on
The price depends on the model and year of the motorcycle, the ECU, the scope of work and any parts. Describe your motorcycle and what you are asking about.
Frequently asked questions
What exactly can be unlocked?
French-market and US-market versions, speed limiters, power limits in the lower gears and the A2 power restriction.
What are some example results?
From the archive: Yamaha FZ1 FR 106 → 150 HP (at the crank), Honda CB1000R 106 → 125 HP (at the crank), Kawasaki GTR1400 FR 86 → 122 HP (at the rear wheel). These are results for specific motorcycles, not a promise for yours.
Can a speed limiter be removed?
Yes, speed limiters are among the things we unlock, e.g. on the Honda VFR1200F DCT and Yamaha MT-09.
What about the vehicle documents?
Derestriction changes the motorcycle's parameters, so remember that it must remain consistent with the vehicle documents.
Will you unlock my model?
The archive examples are only part of our work. Give us the make, model, year and current state (FR or US version, limiter, A2 restriction) and we will reply with what can be done.
