I have FZ-S V3 and it starts vibrating at 70 ... Can I install dual channel ABS in Yamaha FZ-S Fi Version 3.0 BS4? It would not be possible to retrofit dual-channel ABS on the FZ-S Fi Version ...

I am a user. I can assure you the build quality is good. But the suspension is stiff and bumby ride may result in backpain.
