• Drop in ECU replacement so:
  • No wiring or splicing of wires like with a piggyback controller
  • Super-easy, 30-min install
  • Easily “Undo-able” (e.g. if you sell the bike) or transferrable to another bike of the same generation
  • No invalidating your warranty
  • *complete* control over all aspects of your engine: fuel, ignition, rpm limit, cold-start compensation, and on the 2019, also: injector angle, vva-activation
  • make adjustments while the engine is running, over bluetooth from your android phone or tablet (sorry, no IOS).
  • full data logging, so you can review your engine data, also via the phone app

In addition:

• Legal to ride on a CBT/provisional license (unlike a big-bore kit)*
• Actual top speed increase without having to mess with changing cylinders or engine internals, or changing the running characteristics of the engine (as a big-bore kit does).
• No need to change gearing, so no loss of acceleration (like you would have with a 15t front sprocket)
• Distributed from within UK and EU so no “surprise” import duties/taxes and easy returns/replacement if there is a problem.
• UK & EU after-sales support by NorthCust (who is admin of the R125forum and general remote-fixer/tuner of R125s)

*you may still need to inform your insurer if you replace the ECU, check your policy documentation

Oh and just for awesomeness (I *think*) we’re including a quickshift kit with the first 10 orders.

Just to be clear, THIS IS NOT ON SALE YET, but we have the first development units in the country and running on the UK-spec R125, and NORTHCUST are building a map suitable for the UK/EU spec R125. Once that’s done and the devices are ready for sale, they will be on sale VIA THIS WEBSITE ONLY.

So add your email address to the list below to be notified first when the devices are available for sale. Folks on the list will be contacted before anyone else and on a first come-first-served basis.

We are the ONLY UK/EU authorised distributor and we have worked hard to keep prices reasonable but also ensure top quality after-sales support so that you actually get what is promised. Our device costs less than a PCFC or a Powertronic and can do a *lot* more than either.

Please note: At least to begin with there will be very limited quantities of these devices (10 per batch) because I’m doing the after-sales support myself and I want to make sure everyone is properly looked after and happy, and I can only do that if I’m not swamped with requests. We will also be doing them one gen at a time for the same reason (starting with gen 3).

Once we have all the support documentation, installation guides and procedures etc in place, and if there’s demand for it then we can potentially switch to larger batches, but for now, if you want one of these ECUs, it would be wise to register your interest below (it’s just an email list), as those registered will be given first opportunity to buy.

Gen3 / 2019-2021 are the first up!

Not for any particular rhyme or reason, this is just how it worked out, but the first batch will be for Gen3 bikes (2019-2021). Afaik there’s currently zero other tuning options for the gen3 so this should be a nice treat for gen3 owners. Finally make the most of that shiny exhaust 🙂

So how do i get it?
