The maximum power claimed by Suzuki is 65BHP. You readout shows 64, which allowing for variations that occur on different dynos is pretty much spot on. Fitting a PC to a standard bike is unlikely to increase power output much (if any) over standard, but if set up properly may well improve throttle response , smoothness and fuel economy. Where a PC can be useful is if you fit things like a free flow air filter and exhaust, removing the catalyst, then resetting the fuelling may well give you a bit more top end BHP.
