That is exactly what they have told me, that if I place the exhaust open and remove the oxygen sensor and the reducing washer from the intake body, the control unit will understand those parameters and will work without limits. The race ecu is to gain more extra power.
What model of mountain do you have? 301?
Thanks for responding. It was bought in Spain. The motorcycle came in its box with all the instruments placed to pass MOT.
but it no longer includes the open exhaust. Montesa now sells you a separate competition kit consisting of an open exhaust and ECU.
The option they give me is to buy only the open exhaust without lambda or catalyst.
But my question is if the motorcycle will be fine or I also need a control unit.
The current Montesa models already come like this, limited by the Euro 5 homologation.

good morning I just bought a 2024 4rt 301. The motorcycle comes limited with a catalyst and lambda probe. Montesa apparently sells a race kit that includes an open exhaust and an ECU with another reference. That kit is very expensive. I have spoken with a mechanic who works on these motorcycles and he tells me that on the 301 the open exhaust is mounted and the intake body limiter (a reducing washer) is removed and with that the motorcycle is delimited. He tells me that the ECU in the race kit is not to limit the bike, it is to get more performance out of it for competition. Do you know what is true in all this? I don't want to get more power, I just want the bike to deliver what it has to deliver.
