YAMAHA’S 2-STROKE MOUNTAIN PROGRAM

We’ve talked about Yamaha’s HPDI (High Pressure Direct Injection) on this website before.

If you haven’t read about it here you may still be aware of the fact Yamaha owns 2-stroke DI technology and actually produced it for a number of years on its 2-stroke marine outboards.


It’s a totally different system than Ski-Doo’s DI E-TEC but produces very similar results. I’ve experienced this technology on the water and these 2-strokes are flat-out phenomenal engines and have all the desirable features of 2-stroke Direct Injection. They burn very lean, use little oil, produce almost no smoke and make great power.

Our point is this: Yamaha has been getting very serious about the mountain market the last two years. It’s MT-X line of 4-stroke Vipers is getting a lot more attention lately and its 1049cc 4-stroke triple is proving to be a decent performer in high altitude situations.

It’s doubtful, however, the MT-X will steal many Polaris, Ski-Doo and Cat 2-stroke-loving mountain hardcores away from their selected brand. You could say it’s an uphill battle (pun) for Yamaha trying to sway vertical customers into the 4-stroke genre.

A DI 2-stroke, however, would change all the rules. Remember, up until a decade ago, Yamaha was building some really awesome 2-stroke sleds. The 700cc triple in the SRX comes to mind but some of those early 600 twins were also really fast, lightweight powerplants.

Knowing how Yamaha operates, any new 2-stroke would likely be a complete new blueprint and the use of HPDI may necessitate a from-the-ground-up rejig of any engine designed for a snowmobile, anyway.

What’s even more interesting is, with the Viper, Yamaha now has a really competitive chassis to put a 2-stroke in.

Hey, maybe we’re dreaming in Technicolor here but when a company owns great technology and it’s just sitting on a shelf somewhere in Hamamatsu, doesn’t it tweak your brain to think what could be possible?
