Ebola Monkey1 Posted July 13, 2010 Posted July 13, 2010 I followed some possibly bad advise, and bought a 100/90-18 Kenda Challenger tire for the front of my wife's 82 xs400sg. Looking at it compared to the current 3.00x18 it's HUGE. I'm questioning whether or not it will even fit inside the fender mounted. Can anyone advise? I already have the matching tire on the rear, and would really like to keep them the same. I'm actually looking for a bigger rim to relace to the front so I can keep matching tires. Also.... Can the speedometer be adjusted for a larger tire on the 82 xs400? Talking 1" taller tire.
Moderator drewpy Posted July 13, 2010 Moderator Posted July 13, 2010 usually 90/90's, i got a 3:50 x 18 on the front of my tracker, it fits under the front mudgaurd, but I've yet to ride it so i don't know what the handlings like!!

Yeah, I wish I could get this tire in 90/90... I ordered the rear first, got a great deal, then decided to buy the front on the advise that the 100/90 would fit. What size is the front rim on your flat tracker project? Your 3.5x18 SHOULD be close to my 100/90-18. The rim on mine is a 1.6x18, and the rim-tire guide you posted before said 1.85/2.15/2.50 are the permitted rims. Then again it also says the permitted rims for the 120/90-16 I have on the rear are 2.50/2.75/3.00 while mine is only 2.15.

Ebola Monkey1 Posted July 13, 2010 Author Posted July 13, 2010 you sure its a 1.6? 1.85 is standard as far as I know! Positive. I don't know if it's different because it's a "Heritage Special", or what. 18x1.60 Front 16x2.15 Rear If the front and rear hubs were the same I'd lace a rear 2.15 to the front hub, and run a 120/90-16 front and rear.

Lacing another 18" rim to my existing hub, no problem (aside from having never done it). Lacing a 16" rim to my existing hub might be a problem. I can't use the front spokes because they'd be too long. I cant use the rear spokes because they too would bee too long. The front hub is about a half inch bigger in diameter than the rear. I could order custom spokes, but that would blow the budget. Got a link to that virago pic? I can't find it.

If yours is 1.60x18 that is good news for me.

Speedshop Posted July 15, 2010 Posted July 15, 2010 The standard tyre is too big for the rim as it is. I'd say that monster tyre would look very pinched on such a narrow rim. A 2,50 rim is the standard size rim for that tyre, The 1.60 isn't anywhere near an acceptable alternative for that size of tyre.

Ebola Monkey1 Posted July 15, 2010 Author Posted July 15, 2010 That was my concern. I put the tire next to it, and squeezed it down to 1.6", and it's silly close. I did this as soon as the tire came in, and that's why I didn't think it would work. I'm worried it could roll off the rim.

Ive put 100 miles on it with speeds up to 55mph and nothing has felt weird but this is my first motorcycle and i'm a first time rider. It looks like it's on there just fine like it was meant to be on there.. but im a newbie

I have never cut spokes down to a shorter length so i cant say if it would affect them. ( cant see that it would, but dont know)
