After seeing the other thread about a snowmobile engine in a sporty I thought I would pose this question for Erik and anyone else who would like to chime in on the subject. So how about a Erik designed sportbike with an, say 800cc 2 stroke power plant? Rotax is making the Etec motors that burn cleaner then a 4 stroke and make serious HP. Maybe they could reconfigure those into a Vtwin to fit the current configurations. I just love the sound of a 2 stoker! So what do you think? Erik did tell me at the races in NJ last fall that he had a new Etec SkiDoo coming for the winter. | ||

Didn't the E.P.A. ban 2 strokes from the street? | ||

I don't think so. BUT the emissions are so strict that no one wants to dump the R&D into it. Bimota had the 500 in pre-production, then ran out of money. Direct injected I believe. | ||

For street use you are nutz! I don't even think Truck Stops carry two stroke oil... That would really put a kabash on any long trip wouldn't it. | ||
| Ulynut |
An 800cc 2 stroke does sound rather....sinister though. BWAHAHAHAHA!!!!  | ||

With oil injection and a full reservoir the need for oil on a trip would be minimal. But the others are right. Two smokes are pretty much extinct for street use other than mopeds | ||

I buy two stroke oil from my local gas station (FL) for use in garden equipment. I rode a rake of two strokes in the UK. Most any two stroke would come w/a separate oil tank for the 2-stroke oil. Fill up would not be difficult around here. Personally, I really like two strokes in a road/race application. Chris C | ||

There's a very good reason that two strokes disappeared from the streets. Why bring back engines that sound like mosquitoes on steroids, that guzzle gas like they own Saudi Arabia, and leave clouds of noxious smoke in their wake? | ||

The EPA and emissions would be a huge problem for any motorcycle manufacturer to get approved for street use. Purchasing Oil wouldn't be a problem. I rode two stroke motorcycles for years. Kawasaki and Suzuki. Never had a problem getting oil but spark plugs were hard to find away from the cycle shop. | ||

With oil injection and a full reservoir the need for oil on a trip would be minimal. How many miles would a ful res cover? Also you have to think about weight, location, etc. For a sportbike they won't throw a 5 gal oil tank on there, they would try to even out the oil tank size to match the gas tank size. That is thinking from an engineering stand point... And not every gas station on the freeway will have 2Stroke oil. I have been to quite a few that have not have oil... | ||

Well, you could always put the oil in the swingarm I suppose.  | ||

2 strokes are freakin awesome...light, powerful and simple...the rotary valve motors (Erik's own RW was a rotary valve) make a crapload of power...I used to have a Kawi Bighorn (500cc single) that was modified for roadracing,and later for street...It was a hoot to ride, a tire shredding wheelie monster. I helped a friend put a CanAm 250 motocross motor in a Rickman chassis with some sweet fiberglas cafe' bits...it was a terror, could wheelie over in 4th gear. | ||

(Erik's own RW was a rotary valve) It was also a track only bike... I am not against 2 strokes by any means I have ridden quite a few quads and dirt bikes. They are awesome! It just doesn't seem, to me, very prudent for street, this day and age. Of course if any CTOs of any motorcycle companies wanna prove me wrong I welcome it  | ||

Why bring back engines that sound like mosquitoes on steroids, that guzzle gas like they own Saudi Arabia, and leave clouds of noxious smoke in their wake? Not to mention the dirty oil film that collects on the back end of the bike. Sure my 750 triple was a tire burner, but the power band really wasn't what I like for riding the street. I do remember someone trying to tell me that it was smoking so it must have a bad valve. He looked dumbfounded when I shot back that it didn't have any valves, then the light turned green and I left him in a cloud of blue smoke! | ||

If you direct inject a 2 stroke, the oil in the crankcase and the fuel can then be separated. Diesels are big 2 strokes that rely on detonation to light the fuel mixture. Late examples use fuel injection, and have separate crankcase oil. I'm sure there are modern systems that can vary injector pulse, and timing to achieve a very efficient burn. Just as good as a 4 stroke, maybe better. I think a 2 stroke would do great on the track with EFI. On the street?................I would..........an 800!??............maaaaaad power!  | ||

An 800 would drain your wallet of gas and oil. My sleds were 800's. One was a 800 with a 1000 bigbore kit. They were all fuel and oil guzzlers | ||

first it is difficult to compare the mileage of a snowmobile with that of a motorcycle. second an older sled of any make is no comparison for the new sleds with the Etech designs. The new Evenrudes seem to do well with the new technology. Unlike others here, I would like to know more about the new technology available before I comment about the suitability of the new engines on the street. | ||

The old school streetbikes with oil injection ran as much as 20-1 at full throttle...needed on an air cooled motor. A modern liquid cooled direct injection motor would use far less oil...maybe as low as 200-1 under light loads....the fuel economy would still be less....but you wouldn't be touring on it either. A 500cc twin with direct injection, variable disc timing and variable exhaust..no gurlieman pretenses of civility...275 pounds of unmitigated white knuckle adrenaline pumpin' whoopass... | ||

but you wouldn't be touring on it either. But what if I want to? the S1 isn't a touring bike but I have done 850+ miles in a day on it... | ||

no, but it was hard to get into the bar with the bike wedged in my ass  | ||

HAHAHHAHAHA Bads that was funny hahaha and that H1, seems kinda pathetic...but thats just me Jake | ||

I have a two stroke... A V-4 115 H.P. two stroke! I use maybe a gallon, gallon and a half of quick silver two stroke oil every summer in the boat. |
