Could you explain the thinking behind fitting a 200 rear and the 125/80 front?... I've never heard of anyone using anything other than a 120/70.
According to Dunlops site, the 190/55 and 190/60 are best fit to a 5.5in rim which are usually found on a 600. Under normal circumstances, 190s are suited to 6.0in rims but Dunlop rates them differently. Maybe it has something to do with their construction or edge profile. Who knows? The 200/55 according to Dunlop is ideal for the 6in rim.

Lots of guys running DMG Superbike need lots of rubber to make the bike stick under power. The same is true with the 600 class where those bikes make 130+ horsepower. Some make 140+hp. So technically those bikes, even though they are 600s, need the extra rubber of a 190. Just think about all the street based liter bikes that made 130-150hp and we were using 190s all those years. So Dunlop I think made a 190 that was specifically designed for a 5.5in rim. Again I'm just guessing here but it's the only way I can make sense of it.

As far as the 120/80 goes, Dunlop does this to maximize edge grip while at full lean and while trailbraking hard. The taller the tire, the more grip you'll have when leaned over. The flatter the tire, the more grip you'll have while accelerating. The trade off of a taller tire is straight line stability but you'll be more than happy once you tip it in.

That's what I like about you, Turbo. Instead of looking to external factors you consistently look to yourself to provide the improvements first.

"I can't corner the way I want to, I'll improve that."

"My bike feels heavy, I'll lose weight."

In a day and age where everyone's playing the blame game and looking for excuses it's refreshing to see a little discipline, determination, and self-efficacy.
