Listen, I didnt post it up to have an argument with anyone on here... I gave some info to a guy who asked about a few different models of bikes and peoples opinions on them, that is my opinion, if you have a different opinion, post it up dont have a crack at me...Originally Posted by Type R Positive
Less reliable? I'd stop now if I were you.
From your talk I can tell you have never owned a 2 stroke.
CR500 2 stroke = most reliable bike ever built.
2 strokes make more power per capacity than 4 strokes.
Power efficiency goes to the 2 stroke.
Parts are way cheaper. I had to rebuild the top end on my 4 banger, cost over $2,500 for parts from USA. Costs 1/5 of that for a cylinder and piston on my 2 stroke. Bikes are cheaper to buy for starters too. Cost efficiency also goes to the 2 stroke.
Maintenance is also a win for the 2 stroke. I could change a piston out in 10 minutes on my 2 banger. Same job takes 1/2 a day on my 4 stroke. Cams FTL.
Down side is mixing fuel, and using more fuel. Both problems are solved on EFI 2 strokes. Pity only available on outboards at the moment. Replacing rings is also more frequent on small 2 strokes, but my 500 2 stroke needs them replaced like every 2 years, just like my 4 stroke.
As for no 2 strokes in cars? There has been quite a few. Even trucks run 2 stroke diesels.
I never said anything about 2 strokes being used in Trucks or Deisels
And comparing the cost of a 4 stroke parts to 2 stroke parts is ironic... Fair enough 2 strokes are usually a lot cheaper to replace, but this is because they are cheaper to make, and use a lot less parts. But lets not forget you are going to have to replace them more often though, and accomodate for labour and you've got yourself more than enough to accomodate the saving you would have made
I cant think of many higher (more than 250cc) capacity superbikes that would use a two stroke apart from maybe those Aprilia RS's... And I assume with FACTS the reason for this is because they are unreliable or less efficient (in comparison to a 4 stroke)...
Explain me this... If a two stroke is as reliable as a 4 stroke as you say... and seeing that they are 1- cheaper to manufacture, and 2- produce power for less cubes and retaining a higher P:W ratio, then why are the most leading bike manufacturers constantly using 4 stroke motors in their top of the line bikes? let alone the whole range apart from the <250cc'ers
Answer... because they are not as efficient...
