Hi
I heard they are quite good
I just bought a Dr Rossi chip & not impressed
yes my bike is dead smooth on the throttle from 0-11000 rpm
but its also very flat from 0-7k
I dont have lots of engineering exp
But i do have years of road racing & track racing & my bike seemed to ride like an inline 4 750?
Completly changed the feel of the bike & the exact opposite to why I bought a twin
The RP58 felt like it had more torque
This chip also makes the bike feel like its over reving
Hence why I would like to try an aprilia chip
