quickest, fastest, best 50 cc moped/bike around?

Just researching and thought id post up a thread. So what do you think is the quickest 50 around? with mods or without!
i would personally vote for the tzr 50 but what about you guys?

 

These guys.
They got 18.5 horses out of a 50cc engine a few years back. And they pretty much rule the roost with the big bore kits today.

Look at the power.......
They are just up the road from me - and one day I'm going to go mad and have the case machined for their long stroke big bore kit.

 

50cc reg runner with a 180 runner engine init seen a few on eBay a while back

 

That's not 50cc though...

 

The bidalot above started life as a 50.....

 

Yeah bit the Bidalot kit fits onto the original crank case of the 50. so it kind of qualifies as a 'mod' - no?
As well as the fact that the capacity is achieved by a longer stroke, not just a big cylinder.

 

On logbook it is

 

But it isn't 50cc...
You're all missing the point, OP is asking about the quickest FIFTY cc, not 94cc+ that USED to be a 50cc, by mods I'm pretty sure he means anything but capacity.

 

I know but still it's a beast

My mates zip was rapid think it was a 2000

And his sr 50 was fast

 

Ok fair enuf

I just rember my mate getting his zip the wheel wouldn't turn with standard air box so we too it off put k&n on and it shot off like a rocket

 

So just think piaggio the runner engine is one so surely would fit a zip ??

 

I love and miss my old runner and I want her back but don't have 1500 to splash to get her back so I'm finding ways of getting her back to me in some way shape or Form

 

Lol well 125 engine found few for 15-300 same as the 180 I missed out on a 50cc spears or repairs on for 200 so with few extra bits I'd say around 550 if I shop around

 

Drinking monster na that makes me sane

Would touch wacky backy

 

It looks like Parmakit 110cc cylinder can faster. Check out

 

lol, thanks for the suggestions but the whole point of the thread was for 50 cc not 180 runners haha thanks anyway
