what is the fastest 50cc restricted bike?

[27yo kid]

Hey, I'm just getting derbi gpr, Insurance guys would definately check it out if I rode it off a cliff to get it to go above 70!

[Fire_Eyes]

honda have a 2005 nsr50 looks very sporty its made for us youngsters that wanna learn how to knee down but its not allowed on the streets so i dont know anyone feeling risky ...guess not lol

[G]

The NSR50 is quite an old bike I think, and is street legal as far as I know. No reason you can't get your knee down on most bikes; and many scooters.

[Spiral]

Out of curiosity how long would a 50cc de restricted be able to maintain 60mph i mean granted they could probaly do it with a bit of work, but how long could it maintain this till it overheats or just dies the death.

Yeah i have heard this as well, speed fight 50's taking on RS50's and winning, gears on a 50cc is pointless.

Other than the point that they help you get used to using the gears and the clutch which will be helpful when you get a bigger bike, geared 50cc bike are pointless. Even if you plan on going the Max Power direction when you're 17 they will still help you have an understanding of gears and the clutch and how they work, which will be helpful as I don't think you can get a twist and go Nova yet.

Plus the fact that riding with a gears is more fun. Twist and Go is just that - You sit on the thing and twist the throttle, and it goes. Never ridden one myself but i'd guess it must get pretty boring, especially on roads without too many bends. Working the engine is half the fun of biking.

but on a 50cc you must have to work them gears a lot!

Scooter racing at Cadwell at the weekend, im off, you'll see tuned Zip's doing 90mph+, go tell them they are only scooters and are only doing 60 "real speed", you bunch of arrogant c*nts

[Ste]

Well they're not "only scooters", they've spent lots of money on them and will be spending lots of time and money keeping them that way and rebuilding them. So someone who is actually spending lots of money and time and getting a scooter which can be used on a track to go fast for a bit is slightly different to most ped boi's and their K&N filters and a aftermarket exhaust.

[27yo kid]

Guys I have to say I agree with ste here.
Its like getting a kit car (which I have) and comparing it to a racing kit car.
I mean my cars great but the cars they race are more than just kit cars.
Same goes with truck racing.
(besides, I bet they dont whizz in and out of traffic and up on the pavement when they're racing them on the track!)

THAT WAS A JOKE BEFORE ANYONE GETS UPSET!!!

I borrowed a friend's Runner SP50 for 2 months while he was in school and my engine was in pieces. It's a '99 model, original piston and cylinder, completely stock but derestricted and I managed 102 kph / 60 mph (indicated 110 kph, but the speedo's off) down a long, slight hill and was good for 88-90 kph on a flat if I was to duck breeze. It's the fastest stock 50 I've ever ridden, and I've ridden a lot of 50's .

Another friend of mine had an NSR 50 with carbon fibre reeds, a 21mm carb, cone air filter and performance exhaust and was topping 115 kph / 72 mph on a flat for a few months after buying it. Those are correct speeds as someone was following with a digital speedo the first night he opened it up proper.

My point is some of you have some strange ideas about what 50's are capable of. In Bermuda, when you turn 16, you get a 50, whether as a birthday present or from your own pocket. That's just how it is. You can imagine the competition between the guys with the faster bikes and the money dropped on performance parts . So, I've been to a lot of races, ridden a lot of tuned machines, etc, and some of them aren't bad for what they are.

What speed increase will you get from changing from 11T to 12T or 13T

[Clutchy]

100000000mph





Give or take.

Used to have an old DT50.
That went to 47mph and then needle stopped but mates clocked me at 55mph downhill.
Blew it up like but they were cheap to fix.
