To make a long story short. There is no way I can get another bike out of various reasons. Plus I would never get any decent money for my beloved 11 year old.
Now last Year I put Marchesini Ultralights on my F4 and the handling improved dramatically, as might almost every one would have imagined.
Recently I bought even some Moto Corse titanium mufflers.
Now I think I will try to improve the old gal further.
We speak a lot about unsprung weight.
So what is the weight of stock 310mm rotors ?
What is the weight of the stock rear rotor ?
What is the weight of alternatives ?
Your input would be really appreciated and is might interesting for fellow riders.
