MotoGP getting safer?

[White trash]

Yup. I reckon Dajiro Kato thinks they're safe as houses.

The manufacturers supposedly use MotoGP to develop prototype technology which will eventually filter down to the consumer. In most countries you simply can't buy a 2 stroke road bike as they can't (yet) be made to meet emission standards. Therefore it is pointless for factories to spend millions developing 2 stroke technology when it can't be used.

If I understand it correctly, the EPA in the US is working to ban 2 stroke recreational vehicles, if that is correct eventually you won't even see a 2 stroke MX bike, Jetski or Outboard. Not unless someone develops a way of making them clean.

Fuel injection will see the return of the two stroke, but possibly in automobiles before motorcycles!

[Mental Trousers]

That would be direct fuel injection gav. Much cleaner as any air that escapes out the exhaust port isn't carrying fuel as well.

West Australian company Orbital Engines were making 2-stroke engines that met all emission requirements some years ago. I think Mercury outboards uses their OCP technology under licence.

I actually called into the factory years ago looking for a job. The original orbital engine was just put on top of some shelving out of the way. Complex bit of gear but very interesting.

This page has a bit of the history and notes the dates the various manufacturers started using the technology.

Ya beat me too it. He was the first since 93 wasn't he?

Who died in 93?

If im not mistaken nobody has died on the track until kato died well at least not in motogp/500cc

The 2 strokes were trickier to ride - the highside is typical 2 stroke as they spin up and snatch traction again,we don't see as many highsides these days,in MotoGP it's more typical 4 stroke losing the front.It's always been my biggest worry riding 2 strokes,and my DT230 keeps me on my toes - I'm careful not to give too much coming out of turns,just a stutter bump will spin it up to max revs and the snatch when it hooks up again is scary shit.

Thats 73 not 93

[James Deuce]

Still 500cc.

they will be back...garrenty it!

yup... v6 250hp mercury outboard...u can go buy one for the last couple of years....and lotus has built a next to no emissions two stroke as a car engine a few years ago...but never did anything with as its not what the market want...

its also interesting how modern four stroke race bikes are using twostroke technologie from decades ago to increase power and usable power....Hmm...they ain't dead yet!

The 2 stroke won't be a go until they take the lubrication oil out of combustion,this can and has been done.2 stroke diesels have always been this way,and direct injection will allow it to be used for petrol engines.Way back in the '80's Nissan had a 2 stroke with cams,valves,crankcase lubrication running....all it needs is direct injection.

that exactly what the lotus and orbital two strokes did...take the lube out of the combustion chamber...
