To me 2s sleds not in the cards for Yamaha & will address all market segments with 4s just as they have done with the Viper. Who knows what next generation platform will weigh?.... Yamaha has heard the weight issue....LOL.... Could be new engines as well that could weigh less and Yamaha has methods to reduce engine braking. I'm sure they are prepared to offer an exciting new 4s platform to what the market wants...if not why do it?.... they are in biz to succeed & make money.
There is a lot of weight to be cut on 4 strokes. Carbon fiber..small displacement 4 strokes with turbos. But these things also cost a lot of money. The offtrail market is the fastest growing. Only way in my opinion to be cost competetive is with a 2 stroke. Otherwise they will just be too heavy to truly compete.

I would also thing Yamaha would update their 4 strokes into being competitive with the ACE models for efficiency. For the people who want good gas mileage, the yamahas just arent as efficient. Those engines are pretty old technology. I would assume something is in the works.[/QUOTE]
Regarding competing with the ACE models - I think everyone agrees the Phazer needs to be updated. They do though cost quite a bit less than the ACE, so they're not really in the same market. I do think Yamaha is missing an opportunity in the ACE-class - 60 or 90 hp, high efficient trail riding.
