hi there, i am trying to get some technical detail about motorcycle tires: Michelin Power Supersport Evo and the Michelin Power Cup Evo, i need to know the circumference of the tire. for tire sizes: 120/70/17 180/55/17 180/60/17 190/55/17 200/55/17 what about other tire manufactures, Dunlop and Pirelli. Thank you
ok so here are info that i got some time ago from this forum: Dunlop D211 120/70/17 604mm 190/55/17 647mm 190/60/17 657mm Pirelli supercorsa SC 120/70/17 604 mm 180/60/17 656 mm Michelin supersport evo: 120/70/17 604.8 mm 190/55/17 653.8 mm
Keep in mind that these days, the "180" and "190" etc designations are more about marketing than anything else. For example, I believe the Pirelli "180"/60 actually measures something like 193mm. I'm sure somebody will correct me if that is wrong, but it isn't a 180. Not all 180's and 190's are created equally, and that is definitely not the exact measurement...it is more of a model designation.
So for the correct/current info For Dunlop ask Bru For BStone ask stick For Pirelli ask James or Leon For Michelin ask Hirsch
Make sure you compare apples to apples cuz I don't think anybody or bike that goes fast uses a 180/55. The fast tires for 600s are 180/60 or bigger
Ok so here is the answer from Michelin: Michelin Power Supersport Evo 120/70/17- 612 mm 180/55/17- 644 mm 180/60/17- 664 mm 190/55/17- 656 mm 200/55/17- 668 mm
I can't verify the above (don't know,didn't look up), but the Power Cup Evo is 120/70/17- 605 mm 180/55/17- 638 mm 190/55/17- 654 mm 200/55/17- 664 mm
Well, if one tire is 3mm bigger `round, then you have to adjust your gearing. 3And you need to know how much the tire 'grows' at certain speeds and temperatures. And the effect of different tire pressures on cold diameter and hot running diameter. So, if your choice is the one that lets you run your current gearing and chain, will changing to a different one require a different rear sprocket? More chain or less? Inquiring minds want to know.
Hi MELK-MAN, these numbers was sent to my by Michelin for the Power Supersport Evo. i know you use Michelin's a lot but did you get your numbers from the net or a tire supplier? i want to know the height of the tire since it is an indicator for me how fast and easy the bike turns.
this is the official diameter: Pirelli supercorsa V2 120/70/17 604mm 180/55/17 641mm 180/60/17 656mm 190/55/17 652mm 200/55/17 656mm Dunlop D211: 120/70/17 605mm 190/55/17 647mm 190/60/17 657mm D212: 120/70/17 602mm 190/55/17 649mm
