lb/hp is what it's about!
By switching to a cast sportbike front wheel you will be lowering the front of the bike and changing the rake angle. When you decrease the rake angle (making it more vertical) you don't need quite as stiff fork springs. Racetechs website and the new spring rates they give you after you put in your weight assume stock geometry so if you up the spring rate it will feel stiffer yet because of the new rake angle.Not to stress the lengthiness of this discussion thread, but supermotos are a foreign language to me concerning suspension. I'm trying to figure out what would be the best street performance suspension modifications for this build.
I've adressed racetechs website and got;
.58kg/mm front forks (closest .5kg/mm)
.55kg/mm rear shock (closest .5kg/mm)
Progressive suspension springs seems to be the all around, multifaceted, basic everyday rider suspension. I have seen medium and heavy duty springs, but it seems as if the light duty springs are the only ones available for purchase. Sort of makes sense to me to go with the progressive suspension due to the riding style, but can I manipulate these progressive springs to be stiffer through spacers or valving?
Need one of you suspension nutjobs to lay it on me... As I'm forcibly not pulling the trigger, until i get some guru guidance...
Medium, heavy, and light duty springs don't mean much without numbers attached to them. For all I know the light duty spring could be the spring in the blow off valve for your Bandit and the heavy spring could be from my neighbors F-350 (I know this isn't the case). Keep in mind that the stock suspension, rear especially, was really soft from the start. Before I started tearing into XL600 I could bottom it out by bouncing on the bike. Spacers in the forks will allow you to add preload but that only gets you so far.
