Here is a little insight into our in house special project, we jammed a big bore 690 into a 2015 RC 390. It was so succesful that it got 2nd in its first ever race! Here are a few specs to make you dream.
- 290lbs wet
- 60ft lbs
- Uses all RC 390 spares
- 690 duke wheels and brakes 120/165
- Ride by wire superbike harness
- 3mm big bore making it a 732cc
