I'm in the process of upgrading the standard suspension on my '16 until I get the parts together to fit better components and decent sized wheels. I'm looking to fit a cbr600rr shock on the rear and maybe do some work on the front end to firm the ride up a bit.

Are there any quick upgrades that can be done or am I better changing the fork oil for a thicker viscosity and making some preload spacers up for the springs?

Thanks
Paul
