Is the bigger front wheel to better roll over obstacles, or is it just a demented fashion statement? Conversely, does the smaller rear wheel provide any real advantage? Back in the day, Charlie Cunningham built MTBs with a smaller rear wheel- IIRC 20" rear and 26" front. Many dirt motorbikes have a smaller rear wheel. I have no idea why. MaybeCarlFogel does, he used to ride trialsand the like. Dear Tim, Sorry, but we fooled you. Don't feel bad, since 9 out of 10trialsriders will mistakenly insist that their front tires are bigger. After all,trialsmachines use 21-inch front rims and 18-inch rear rims, so the front tire must be 3 inches taller, right? Nope. Look at this 2007 GasGas TXT 300cc, which has the standard 21 x 2.75 front tire and 18 x 4.00 rear ti http://i16.tinypic.com/4pl4yhk.jpg You can't tell the front tire from the rear with a yardstick on atrialsmachine, particularly if the rider's weight is squashing the lightly inflated tires. For practical purposes, the front and rear tires are the same height. In fact, the height of the tread blocks on a particular model of tire has more effect on the tire height than whether it's a "21" front or "18" rear tire. On the front, the narrow 21-inch rim mounts a skinny 2.75 tire. The combination is tall enough to roll over obstacles easily, but still light enough to steer, bounce, and pop up in tricky places. The rim is strong enough because the leading tire takes less impact, carries less weight, and has more suspension. On the rear, the wide 18-inch rim mounts a 4.00 tire, which is so thick in cross-section that it ends up just as tall and willing to roll over obstacles as the dainty front tire. The 4-inch width gives traction for the engine, the huge increase in cross-section gives more pneumatic suspension at the same 4~6 psi (think 700x38 versus 700x21), and the massive rim and tire withstand ~400 pounds of rider and machine slamming into waist-high rock ledges. Since the rear tire steers a gentler curve than the front tire, the enormous increase in weight doesn't hurt handling. That's why the original 19-inch front and rear rims were replaced. They were fine for pavement and okay for fairly smooth off-road riding, but too heavy and clumsy for the front and not heavy and strong enough for the rear when riders began bouncing over fallen logs and big rocks. Cheers, CarlFogel An email asked whether non-trials motorcycles also have tires with different size rims, but the same effective tire height. Non-trials motorcycles are a dark and bloody mystery to me, since I can't see what purpose they serve, but I grabbed the first picture of a motocrosser that I saw on the Honda site and popped it into my etch- a-sketch--er, sophisticated computer paint program: http://i11.tinypic.com/67sni44.jpg The rims turn out to be 19" and 21": http://powersports.honda.com/motorcy...lId =CRF450R7 You could argue that the front tire here is a tiny bit taller, but that may be due to the picture angle, tire inflation, or my etch-a- sketch skills. It's certainly not 2 inches taller. Cheers, Carl Fogel |
