Huge difference while riding! Man, the stock tires are crap! U realise that only after u get rid of em!

Got one qsn - is it ok for the brake pads to be brushing slightly against the discs? Sorry to be sounding stupid, but just curious!

-Kid

You mean like, if you get the wheel off the ground and spin it, you hear the pads lightly scraping against the rotor?

Yep, that's normal.

Speaking of BT45s, what's the recommended tire pressure for them (110/70-17 Front, 140/70-17 Rear)?

Thanks!

Yes, Kerry, the slight rubbing when I rotate the wheels freely. Thanx for the clarification - I was worried that something was wrong....

Scorpio, I have stock sizes for the BT45s and have the stock tire pressure - 33 front, 36 rear.

I just go with the standard 33psi(front), 36psi(rear) with my BT45s

And yeah...they rule.  

Yeah, I just got my BT45's last Thursday and you're right - what a difference.  Much stickier.  I couldn't be happier.
