Excellent thread! Even after upgrading my 2015 rocket at Carpenter Racing, I purchased a BMW S1000RR to carve canyons here in Colorado. The ride of the S1K is totally different than the rocket. Surely not gutless. It is not modified other than an exhaust and an ECU flash. It has nowhere near the torque of the rocket but since its power to weight ratio is so vastly different, it still scoots very nicely. The BMW was also designed to perform well in areas the rocket was not designed to perform well in.
I think you would have a great time having a Z900 or similar to scoot around on. It reminds me of the saying "its more fun to ride a "slow" bike fast".
