The rear wheel is also a half inch thinner at 5.5 inches while it uses the same 180/55 tire, a change Aprilia says improves handling and increases turn speed.
What?! Are the Aprilia Engineers Bloody INSANE!!!!!? Motorcyclists will Die in Droves! Too-small of a rim, a 180 has been carefully Engineered for a 6" Rim! Flaming Death! Dire Consequences! The guys on MO said so! FLAMING DEATH!!!!

Sure it's going to turn faster. You can tell by the picture the the bike's about to fall over already.

Who said so? 180 rear tires have been fitted to millions of 5.5-inch-wide wheels?

Duke needs lessons in Sarcasm-Recognition!

I was referring to an earlier thread about someone putting a larger tire on a rim that was hard to find the stock size, and the sounds of Impending Doom and protests of Engineering Faux Pas many here were making about it. In this case, Aprilia's putting a smaller rim inside the same tire.

I can only assume that, because the guy who was asking about it hasn't posted-up with the results, he must have died in a fiery crash 2-miles down the road from the tire shop............

It'll be interesting to see if other manufacturers follow suit. I can't believe that Aprilia figured out something that hundreds (if not thousands) of MC engineers hadn't already figured out. I'm a skeptic. I believe the engineers know what works best. My guess: Aprilia estimated saving one hundred million dollars (well... not really that much, but $$ nonetheless) by using a narrower rim.

Aprilia isn't doing anything new by fitting a 180 tire to a 5.5-inch rim. Putting a 180 on a 6-inch rim is weird, as a 6-incher is usually fitted with 190 tire. A narrower wheel will be lighter than a fatter one, so there was no point in adding weight (and a little bit more cost by the use of more metal) with the fatter rim. The Shiver doesn't have enough power to require a 190, and a bike always steers quicker with a 180 compared to a 190.

Ah, yes, sarcasm. I'm not so good at it. Please always use a winkie face!

If my memory serves me correctly, the original thread (argument) was about putting a 140 or 150 series tire on a 130 series rim and whether it was "safe" or not. Some were in favor and some were against it.

Of course, I am getting older, so...
