Amazing have you thought about designing one for the F4 :stickpoke
man you are good at those things!! i still have the corse one as my desktop, and the only thing that would replace it is an F4 one!
That will hold us over for sure.
On a side note, what is the redline on your 675? I had a chance to ride Wa2fast's 600 at Bubba II track day and was amazing at the amount of revs it could take. It made me want to get a dedicated track bike less than 1000cc's but i would like less revs. Totally random i know!
