Stage 2 ECU Flash Upgrade with BT Moto Velocity Stacks - BTM-R1250-S2

About the Product

*STAGE 2 REQUIRES THE PURCHASE OF STAGE 1*

2019-2022 BMW R 1250, STAGE 1 PURCHASE REQUIRED FOR STAGE 2

Coming from our Stage 1 upgrade of more power with better rideability, Stage 2 offers so much more! Our custom velocity stacks and revised tuning for the OEM widebands (on applicable models) not only gives a dramatic power increase but also overall better and more consistent rideability. Our easy to install custom velocity stacks don't shift the powerband over and decrease power down low. We managed to make more power everywhere, as we know these bikes aren't for racing or staying high in the RPM band. Careful consideration was taken in every aspect of Stage 2 to fit the bikes application and riding style.

We are confident Stage 2 will be a dramatic change in your bike and leave you smiling every time you get off the seat.

Stage 2 was developed and designed TO WORK WITH BT MOTO VELOCITY STACKS. STAGE 2 CANNOT BE PURCHASED WITHOUT OUR VELOCITY STACKS.
