I've cked the tire threads but I couldn't find one that actually tells me if the following tire will fit on a 2005 1300R. So sorry if this is redundant. I'm looking at a front tire -- Metzeler Marathon ME 880 front tire, 140/70-18 . Can anyone who knows about tires tell me if this size will fit my bike Without any mods? I think the stock is 140/80-17. I have the stock R cast rims with a dunlop on it now. If I'm correct, the 17 at the end is the width of the rim? but what about the other numbers? What do they stand for? Will the Marathan size I'm looking at fit my bike w/o trouble? I've heard a lot of good reviews about the Metz. I don't ride a lot and the price on this tire is really good. Thx for the tips.
