Re: mods question....
I recently bought the same bike, bone stock with low miles....except for nice rearsets installed. Here is what was "bang for the buck" .... in my evaluation:
I was initially disappoined with the handling.... coming from a CBR600. So this is what I did....
1. Ohlins springs for $120. Totally changed the feel of my handling.... along with some careful tweaking of the rebound and compression damping.
2. Scotts steering damper. Really stabilized my handling in general and gave confidence.
3. Bridgestone BT002r Streets. Best tire I've ever ridden on and I have ridden for decades. Can't say enough about how much stickier these feel.... And I have had Pilot Powers on a CBR600.
4. Helibars. BIG comfort improvement and still looks stock.
5. Morwaki slip-on. Called "Zero" in the USA, it is hand made in Japan expecially for CBR's - no power commander needed, sounds great and added just a bit of sharpness to the feel of the power.
On the street I found little need for more power that comes from lower gearing. What it already has is extremely street friendly and yet big power. This baby can already haul the mail.... unless you plan to use it on track....
The only thing I still consider is an aftermarket shock... not so much for handling, but for a smoother ride... which would still likely translate to better handlig as well.
