From reading some of the tire posts it sounds like sizes arenít the same from one manufacturer to the other, some posts mention 4.10 for this bike. Front should be Shinko 2.75 right?
I'm currently running 80/90-21 and 120/80-18 which translate to 3.1 and 4.7 inch widths. If I ran knobbies for more off road I wouldn't go any bigger but I run Pirelli A/T Scorpion MT90 front and rear (thanks again Dan Oaks) so one size larger should fit. At ~23k miles the rear tire is finally getting bald. Slightly longer legs would suit me fine so that's my Q1 plan. The front tire still looks good so I'll defer that. When I do a size larger may not quite fix the speedo but it should be closer to actual.
