In 2006 a 50cc bike did 121.439mph at Bonneville. 137mph one way.
They sort of used an Aprilla engine. I doubt there was much left that was Aprilla in it though.
But before you get too excited, the record to beat was set in the netherlands in 1981 at 137.961 mph using a 50cc streamliner 50cc motorcycle.
Now with scooters some guys are reporting going 65mph or faster. One fellow with a Nitrous system got over 80mph.
65mph looks realistic as one of those water cooled Kymco's with minimal mods can do that.
Aprilla has this on their site about setting a speed record of 84.36mph on a 50cc road race bike.

After they worked out the bugs of course, years ago, the Japanese dominated the 50cc GP races with their multi-cylinder 50cc GP race bikes.
I think that my best memories were racing 50cc road racing bikes many years ago, at least until I got too big and fat for it. I grew up. Like these here:

METRAKIT SETS TWO NEW AMA NATIONAL RECORDS FOR A 50CC MOTORCYCLE
John Buddenbaum and Eric Noyes of Sunnyvale California with the support of Metrakit USA and Cycle Imports INC. set two AMA National Records with a 50cc motorcycle streamliner. The motorcycle was designed and specially constructed by them in John’s fabrication shop in Palo Alto California. Powered by an Aprilia 50cc (Minarelli AM6 engine) modified with METRAKIT pro race engine parts.
On Monday September 4th at the International Motorcycle Speed Trials by BUB held on the Bonneville Salt Flats in Utah, Eric Noyes drove the streamliner to a new AMA National Record for 50cc streamliners on gasoline (S-AG) with a flying start one mile two way average of 121.439 mph.
On Thursday September 7th John Buddenbaum drove the same machine, modified to run on fuel, to a new AMA National Record for 50cc streamliners (S-AF) with a flying start one mile two way average of 133.895 mph.
The highest AMA record for a 50cc motorcycle was set by H. Muller at Bonneville in 1956 in the Blown Fuel class at 121.700 mph (S-AB) using a machine built by the NSU factory. This class no longer exists, current safety regulations mandate equipment that makes today’s streamliners bigger heavier and safer than the old classes.
The highest recorded international speed record (FIM) for a 50cc motorcycle: flying start one mile average speed was set in 1981 in Lelystad, Netherlands by Jan Huberts at 137.961 mph (222.026 km/h) with a streamliner powered by a
Kreidler engine.
John and Eric will be participating/competing in the 2006 Bonneville World Finals October 11th -14th. If they can add just over 4 mph to their last record performance they will then hold the distinction of having built the fastest 50cc motorcycle ever officially timed.
