yamaha has been producing high pressure direct injection 2 strokes power boat engines for quite some time. I wonder why they dun want to apply this tech to a new range of 2 stroke bikes? I know they have stopped producing 2 strokes due to the company's policy on conserving the environment. But with the new HPDI tech, there is loads of potential to be unleashed!

 

you get all the usual pros from a 2 stroke and furthermore, with HPDI, fuel consumptions is improved by 50%, pollutants is reduced by more than 75% and power is increased further by 10%. has any manufactures produced HPDI 2 stroke bikes yet?

 

eagerly awaiting this tech to arrive! i'll definitely be the first one to bite!

I'd bite the bait too if they start producing dem bikes

seems like a lot of people are commenting on their blown pistons in hpdi engines

[zyrofillica]

u mean their boat engines? mmm maybe that was due to lack of lubrication in the upper cylinder? before yamaha implemented the design of the porous lower piston ring?

Fuel Consumption reduce by 50%, yet power increase! Wah where got so good one, surely got some drawback.. hmmmmm... more wear n tear?

the figures are comparing the old tech 2 stroke with the new HPDI tech. i would say drawback is more components and increased weight/size of the engine. This is again comparing with the old 2 stroke.

Well, this is very interesting, read about it in the BIKE magazine.

Obviously, Lotus is coming up with this new 2-stroke engine, as seen in the article below:

Wait and see...

this got a lot to do with politics and marketing.

lets pray together for 2t technology to rise again.
