Off road wheel sizez?

Recommended Posts

I'm bidding on a set of talon/excel wheels for my DRZs model which has pretty much been transformed into a pure off road bike: IMS tank, remove all the extras, lighter weight parts, 13/47 gearing, etc. I figured the wheel set would be a nice addition and good weight savings.

My question is regarding rear wheel sizes for off road riding. I know most mx bikes come with the 19/21, but the drz comes with 18/21. I understand that a taller hoop will roll over the bumps easier so with that thinking would a 19" rear wheel make sense?

Are there different schools of thought for off road wheel sizes or is it pretty much standard, 17" for supermoto, 18" for on/off road, and 19 for dirt?

You know, I usually just ride the bike and don't think about such things, but now that I'm ready to plunk down some cash for a new wheel set I thought I should look into it.

Thanks,

Tom

the actual overall size is the same on most 18 and 19 inch tires once mounted. MXers just use the 19 for less wall height. Do not try mounting a 19" they are a pain. Stick with 18" for mx and offroad you will be much happier overall. Super Moto uses 17" for one reason - tire selection.

Great, that's what I needed to hear. Now I'm not going to worry about it.

Thanks, Tom

Off roaders use an 18" wheel for one main reason....reduced pinch flats. With a 19" there is less side wall to absorb impacts.

I suppose the smaller rear wheel (18) would be better for low end and quicker manuvering. I think the 19" wheel would make sense for relativley smoother courses of MX and SX (groomed tracks) as apposed to the ruts, rocks and roots of off road riding.

Either way, if the price doesn't go through the roof on the talon/excel wheelset I'm bidding on then I'll be psyched to put replace the stock wheel set. Now I just have to recover from my broken leg.........................

The rim sizes are different, but not the overall tire height. Therefore bottom end and handling will be affected very little. Some from the difference in weight but I bet that is minimal.

Not sure if the wheelset is going to be any lighter either.

It was my understanding that the excel/talon wheelset was a big factor in overall weight savings over the stock wheelset, not to mention reduced rotating weight. If they're not that much lighter then maybe I've been misled. What is your understanding about it - since you mentioned it?

IIRC, the talon hub is a lot stronger than stock but not much lighter. But that is relying on my rather feeble memory...
