Can an Rs125 engine fit into an RS50 frame?

[rieju]

lol. a 125 i would asume would beat most saxo's and corsa's to around 70mph i would guess aswell!!

[sheehan]

no idea if a 125 would fit in a 50, but a rotax 257 (250cc) engine will fit in a 125 needing only a top engine mount fabricating, this gives about 50bhp and 130 mph with good gearing.

So the real question is....

Can a RS250 engine fit in a RS50?

im shore iv seen it done, i work at mallory park as there main photographer so see bikes race round there on a regular basis being such a small track weight is critical amd im shore about a year ago i was talking to a guy who was racing such a conversion he was going on about the saving on weight due to the smaller frame, altho i carnt see it making that much difference on a road going version and as for doing vice versa to make the worlds best looking lerner bike if your restricted to a moped i dont think its aloud because your not aloud to mod your bikes and i would consider it to be a pretty big mod i might be rong on that one tho but either way yea would be the best looking 50

hay just red the rs250 in a rs50 bit now thats just crazy but i like it lol

[Makin65]

Ahh but the real question is.. has anyone ever put a 1000 in an rs50.. i mean all you need is a cheap engine from the scrap yard . Yeah your prob all readin this like . But that would be ace, burning a cbr 400 off at the lights lmao

[patchb]

errr no the frame would probably snap from the power and it clearly wouldnt fit into the frame. Why do you say burn a cbr400 from the lights when if it could be done you could burn virtually anything from them.

[slasherslade]

'Cause CBR400 riders are more likely to be cocky racers. 1k riders just smile at the sight of another bike on the road.

....or so i'm told.

[Makin65]

Ahh.. well said slashershade.. theres your answer .

On a lesser note, my clutch is slipping . New clutch I think, only done 12000km though

wish i had a pegaso 650 motor to stick in there

[Benneyboyg]

too be fair nothing is imposible , im fitting a dt 125 lc engine in my rs , but i am also fitting uprated running gear and brakes, etc

[AF1-Racer]

a 1000cc would never fit i doubt anything above a 350 would...
it's also plain stupid to go above 125cc in a moped unless you can seriously add some extra strength to chassis.

Although i have seen a Honda NS1 (74cc) that head CBR600RR forks and rear swing arms (looked so sick that i wanted to buy that thing instantly).
if you could take something like that as a basis it would be more safer to fit a 125+ engine (something like a 250-350 cc)

[RsBurgess09]

me and my mate did it with the old shape rs took lots of cutting and welding, and no its not safe we had ours for about 3weeks and the frame bent cause of the weight

[MasterTenerife]

the REAL quesstion is, could you put the hayabusa engine on the RS 50?

[RiejuR51]

the real question is, are you as thick as you just made yourself look
