Hello, there is obviously a relationship between the weight of the rider and the quality of the handling, otherwise all Moto GP's would only have the same suspensions...
As for me, I weigh 105 kg and, a priori, the springs are not strong enough, which is why I am looking to change those of the fork and the rear shock absorber.
As for Showa, you shouldn't believe that the elements mounted on the Rocket are top of the range, they are of decent quality, nothing more. I have Öhlins on my Ducati and WP on my Husqvarna and I can tell you that it is clearly above, if only by the quantity of possible adjustments !
Afterwards, I admit that I drive like an a*******...so I need ******* suspensions !!!
