More low-end than an I-4, along with cooler sound.

Also, less vibration than a twin under full throttle, and doesn't feel like it's going to stall out or break its connecting rods if you lug it.

maybe if someone other than triumph made them, everyone I know with a 675 for a daily ride has had nothing but problems with them.

Really? I could have sworn that I read that it's a lighter combination... Hmmm... I'll have to check.

I don't think it weighs more or sucks up more power. But it's quite complicated keeping the proper tension on it, that's why you can't just change pulleys. Plus iirc race starts are hard on the belt cogs.

Yea, I've heard the same but conversely, the 1050 seems to be okay...:idk:

So what did you think about MotoGP having twice the displacement the 500 2-strokes had?

No problem with that because everyone switched and they all have the same type engine and size.

How many do you know?

What kind of problems?

I've owned 2 1/2 675's and have only had one problem that was factory error.

I thought that EB had come up with some innovative tensional system that eliminated drive line lash.:idk: Besides, race starts are just as hard on aluminum sprockets aren't they?

I'm a little late to the party here but...is this thread really about Buell racing their liter bike against Japan and Italy's 600cc bikes????

hahahahaha, that's the lamest thing I've ever heard. How pathetic is it that America still can't build a bike to truly compete with Japan in the 600cc and 1000cc categories on the street AND the track?

If Buell is so great why don't/can't they simply build a powerful enough 600cc motor to compete with???!??!?? Pathetic.

Well first off, Buell builds street bikes and THEN decides to race them for the publicity......Unlike the Japanese who build bikes with a priority on winning races as the first priority.

Also, if America wanted to, I'm sure it could build an inline 4, but of course it would be 10-15 years before it would have the quality of a Jap engine. Unless they just outsource it like they usually do :lol:

Beat me to it! If the entire class starts running 1125cc bikes then okay.:lol: Besides, MotoGp is a prototype class. They give you the rules and you build a bike based on what you think is the best set-up... Hmmm I4s have done pretty well in that class too, don't remember any V-twins winning lately.:lol:

Damn, my brother!:lol: Exactly my point, they go on and on about how much "better" their bike is but when it's time to prove it....:whosr:

I-4 and V-4 are running in MotoGP, but they at least have the same number of cylinders and the same displacement and roughly the same HP.

A belt is pretty wide, and kinda thick, so I'll bet $20 it's heavier, lol.

Also what is the fastest bike with a belt? Maybe the V-Rod? How fast can it go? 150? I'd be scared to go faster than that with a belt, lol.

The Ducati is a v4, and the RC211 Honda was a v5.

The first year that both 500's and 990's ran together the 990 of Rossi smoked the 500's. Aprilia tried a 3, but couldn't sort the bugs out and make the weight reduce a 3 allows work to their advantage.

And yes the rules in MotoGP gives a weight break to reducing the cylinders, because more cylinders make more hp.

Even if they didn't have the same hp, it would be up to the teams to change their set-up or get their bike up to speed. Kinda like Rossi did when he left Honda for Yamaha. Instead of being like Biaggi... man that must have hurt! He left Yam for Honda and got beat there too!:lol:

He did, but it's based on the pulley sizes.


And I don't know, but probably not.

Which brings up a good point. Why aren't teams building a 600cc V-8? I bet that would be a monster of a motor.

Rules and packaging.

Look at the evolution of F1 engines.

Hell look at what Honda use to race... Honda_RC_series
