Frequently asked questions
Which vehicles is the Kappa KR2139 fitted to?
According to the Kappa 2026 catalogue and Kappa dealer area, the KR2139 is fitted to the Yamaha Tracer 900 and Yamaha Tracer 900 GT produced from 2018 to 2020. It is a specific mount for these motorcycles and should not be fitted to Tracer 9 models from 2021 or other models. If in doubt, send us the frame number and we will check it.
Do I also need to buy the plate?
Yes. The KR2139 is the mount only and must be combined with a plate sold separately: Kappa specifies the MONOKEY® KM5, KM8A, KM8B, KM9A or KM9B plates, or the MONOLOCK® KM5M or KM6M plates. With the KM8A, KM8B, KM9A and KM9B plates, the stop light kit and remote opening for the top case cannot be fitted.
