Yeah, the pista comes with a **** ratio as it has only one skid patch as well.
I have a Swobo Sanchez that I use a 48/17 on now, and it's a lot easier to control, and my tires don't dissolve as fast.
Sanchez stock ratio was also 48/16.
I recommend a Pista, by the way... or a Sanchez if you're willing to pay a little more for a few better components, and are worried about things like toe overlap (
