Getting ready to pull the trigger and order but want to verify before. Im putting 120/70 21 on front and 180/55 18 on back have the new rims sitting here just need the rubber. Ive been reading and re-reading threads I want to make sure its ok to run these on front and back or is mixing required such as Venom up front/cobra in rear?

 

I ran a venom up front and a storm in the rear on my street bob with great results.
There is no problem with running a bias and radial combination on a bike.

 

If you've got the right wheel widths then there's no reason to run anything but matching front and rear, personally I wouldn't mix radial and bias tires. I'm running Cobras front and rear, 130/18 on a 3.5" wheel and 200/18 on 6" wheel, they ride great and look just as good.

 

Sod father don't mean to change subject, but what rms did you get?

 

Cobra Venom tires stick to the road like glue.
Traction for sure.

 

Do you mean that both the Cobra and the Venom stick Luke glue, or just the Cobra? I have a Venom that I'm mounting on the back, but I was thinking of putting a Cobra up front. I just like the look better than the Venom front.
