what is the fastest 50cc restricted bike?

[mrchips]

When I dumped the clutch into 2nd on my MT50 I felt the forks go light - probably more of bad clutch control than power! See when I cleared out the port on that thing but, boy did it fly. Up to 40 in a few seconds.

lol bak to the topic guys, we seemes to have strayed a little, people have sed that some restricted bikes can top 40mph is this true. and wud a aprilia gpr be able to go 40mph i restricted form?

[JonB]

You don't get it, a restrictor only lets you go 33MPH, in some cases it doesn't work very well, but I don't think that is dependant on the bike, it depends how they are restricted.

If you really want a 50 that goes fast then you will have to go down the derestricted group anyway.

Restricted 50s 30mph tops de-restricted 60mph pushing it tops. Like it or lump it.

my brother had an aerox 50 and it pulled 40 (just). he then got new clutch rollers and it pulled 50 with scorpion exhaust. it could equal cg's and c90's easily. becasue of the new rollers, it lost some of the grunt (ahem) at the bottom end, but if you yanked it hard enough, it would still come up. i saw some maniac come past while i was in a car on an rs50 and he just went into a huge wheelie, like biaggi atbrno 1998. it did look cool. goes to show that you can wheelie anything, but i'm still struggling to sustain a clutch wheelie on my gs125

to get to 50mph the bike would have been de-restricted unless the restrictions were in the exhaust and they were removed when the new exhaust was installed

[Reano]

as far as i know, when a 50cc is de-restricted, its not classed as a scooter, its classed as a bike, which is what makes this illegal.

prove me wrong on this if you like.

[simon1221]

you can class it as a lawnmower if you like it still doesnt make any difference

16 year olds can only ride a bike of up to 3bhp

derestricted 50s are about 5bhp, so it is illegal for a 16 year old to have one, but about 95precent are derestricted, cos i think being restricted to 30mph is dangerous when cars are flying past at 60mph

17 year olds on provisional are allowed up to 15bhp (i think), so to have a derestricted 50 at 17 is fine

[Reano]

every single time a thread about 50cc's is started in the NEW BIKERS forum the thread is flooded with "its illegal to do this, at 16"
i was proving the point that 50cc's are not scoots when thier de-restricted, which is why 16's cant ride a de-restricted 50.

and i dont appreciate my bike being called a lawnmower, thank-you, in fact, im kinda pissed that you came in here, in the new bikers forum, and said that.
who gives a fuck if any of you have bigger bikes? i dont, it takes no skill to do 90mph+ on some big arsed machine.

i agree with lorrydriver tho, scoots look gay....remind me of granny transport....

i have a sports rep, but i dont pose on the thing at all, i use it to get from A to B, i never chose the bike, i was lucky enough to have it as a surpize birthday present, and something my dad worked hard to buy being called a lawnmower really does tick me off........specially if he cuts lawns for a living, which he does, so i cant see how the fuck you can compare a 50cc to a lawnmower.


no matter what 2 wheeled vehicle you own, everyone poses on it, so calling kids with race reps just "posers" i think wouldn't be right, in fact, i would think kids on race reps would more then likely enjoy thier experience on 2 wheels and hopefully stick to the hobby as they get older.

give the new generation of bikers a fucking chance for christ sake.

[JonB]

Reano, chill, we get it all the time, we are not l33t. Some people even go as far as saying we aren't even bikers. Though the last time I checked my ped had 2 wheels.

Just ignore them. Or Agree.

heh, im not agreeing to something i dont agree with

You can whatever you want to, scooter or bike, at the age of 16 as long as it doesn't have an engine above 50cc and it can't do more than 30mph (well something like 50kph).

[simon1221]

i didnt say your bike was a lawnmower i said you can call it whatever you like

"you can class it as a lawnmower if you like it still doesnt make any difference"

i apologise completely if you think my reply was personally directed towards you, it wasnt, im just saying it isnt classed as anything different if it is derestricted

im sorry i didnt know what your dad does i was just picking a motorised example, so dont take it personally

im sure he did work hard to pay for it ive worked hard all summer to pay for mine


and btw i have a gilera dna which i got 2 months ago, is a scooter and makes me look silly but i dont care, as i am not abusing new bikers, just explaining what i thought were the rules

[Reano]

ahh, no worries simon, my post wasn't directed totally at you either, but at everyone who uses that "sarcasm" in thier posts about 50cc's (excluding ste's recent post).
was my fault for snapping like that at you, which i shouldn't have, for which i am sorry

what can i say?, im easily frustrated

[simon1221]

ok dude no worries

[Wave2k]

its the same for people with 33bhp licences and 16 year olds

most 50cc peds are deresricted

and most people with a 33bhp license go above it

its all illegal and it makes ur insurance invalid

its ur own risk, but i say to hell with it

They'll only inspect if it is a sizeable payout, if you crash into a new Jaguar or something I'd expect them to have a look over your bike.

[binge]

I wouldnt quite say it does a ton. ive got a mate whos got a Derbi GPR (all the same) with a FULL metrakit on it (75cc) and he can just creep past my on my speedfight 70cc at top speed. my speedfight has been clocked flat out at 69mph. So that means his GPR probably does 72 - 75mph. Im not being bitchey or picking but i doubt that a 50cc would be able to top 87.
I think somebody is lying.

[Ste]

With a 75cc big bore kit it is no longer a 50cc bike.

There is no real chance of getting a 50cc to 87mph without spending stupid money on tuning it, or throwing it off a cliff and measuring it with a radar gun on the way down. Single use 50cc though.
