I recently purchased a 2017 Roamer, and in reading as much as I could about this model, noticed that there was a power upgrade in the engine at some point.
Can anyone tell me what these power upgrades involved? Was it a re-map of the fueling or something more involved like cam timing? Of course, I'd like to improve performance, so I appreciate the info. Thanks.
 
Please stay in the correct category (now moved), and try a search first. Short answer is they adapted some of the V85TT engine tech (though cheapened out somewhat with a pressed crank and 1-pc rods), and they stayed with the small (scooter based) ECU/Throttle Body through the E5 model. E5+ may be different assuming it will be the same as the V7 updates (more V85TT tech and larger TB & ECU).
You can see all we offer linked below (and the STORE link at the top of the page);
