World records with 50 cc bikes.
Record bikes - year by year1951In 1951 the Victoria Werke attempted to exceed all previous records with this streamlined bike. Driver Georg Dotterweich managed a speed of ? |

Also in 1951 a record was set by Italian Ugo Tamarozzi driving a 4- stroke Cucciolo (Ducati). The lightweight bike reached an average speed of 66,411 km/h over 24 hours and the 48 hour average was 63,209 km/h. Another attempt in 1952 made the Cucciolo reach 77,753 km/h in the 1000m - flying start category. |

 NSU made a series of land speed record vehicles, all designed and build by Gustav Adolf Baumm. It was competing in many classes, and in 54 a 3,4 hp 49cc 2-stroke took the Baumm I to 127 km/h. |

The 48cc 4-stroke powered Alpino broke some records on the Monza circuit : A 500km average of 71,2km/h
and a 3hr average of 82km/h Below Vaifro Meo designed streamlining   |
  |
Vaifro Meo took the Alpino to new records in Buenos Aires : 1000m standing start: 76km/h, and 1mile standing start: 77km/h. |
Aermacchi tried with this Lino Tonti designed streamliner, to set new records in the 50 and 75cc categories. The windtunnel of the Aermacchi aircraft division, were used to create this streamliner, and power came from a double overhead cam single. The 48cc 4-stroke had a bore and stroke of 40x39mm, and delivered 7hp at 12000rpm, to the 18" wheels through a 4- speed transmission. Springtime 1956, Massimo Pasolini did break records, at an autostrada near Milano.

1956In 56 NSU visited Bonneville Salt flats, bringing the Baumm II, and now a supercharged 13,5 hp 2- stroke, powered driver H P Müller to 196 km/h. |

1958Italian Armando Pessina used a Motom for recordbreaking on the Monza racetrack in 58. The 4,5hp 4-stroke managed an average speed of 82,7km/h over 12hours, and 88,8 over 24hours. 1000m speed with standing start was 82,4km/h. |
 |
| Arrigo Remondini drove this Remondini 50 to a speed of 96 km/h. Where and when ???? |
 |
1959Demm1 and 2 show the record breaking Demm of 1959. Riders were Eraldo Tonelli, Piero Bernardi, Bruno Jacopini and Giuliano Franchi. The record over 1000 km was 98.8 km/h, and over twelve hours it was 99.3 km/h. The engine was a two stroke (Demm was mostly known for its lovely little four stroke engines), with a bore of 41.3 and a stroke of 37.1 mm. Power output was 4.5 bhp @ 9000 rpm. Here, again, no expansion pipe! J.Kortekaas 2006

1963On the Monthlery track a french team, beat the 12 hour record now averaging 113 km/h. Engine : Vap Sachs. Driver: Jean Pierre Beltoise.  |
 |
 |
 |
| November same year, the Garelli factory turned up at the Monza Autodrome. The six drivers were : Marchesani, Pastori, Patrignani, Pernigotti, Spinello, and Zubani. The engine, a much modified Garelli Junior 2-stroke 40x39mm were strong enough to retrieve a number of records. |
 |
 |
 |
 |
Average speed achieved over 6 hours : 121km/h, 1000km average : 117, 24 hour average : 109km/h. |
1964 |
|
| Americans used the Garelli engine too and Alan Richards created this SCTA Class I streamliner. Miniscule in appearance and the cramped interior made the builder name it Claustrophobia! The streamliner was build from a wing tank, and running the Garelli engine on methanol, made it produce around 10hp. Driven by Warren Roll the little bug reached a speed of 55,62 mph. |  |
 |
 |
| November 64 at the Monthlery 2,5 km oval, Kreidler turns up with a strong team, determined to set new records. Drivers: Hans Georg Anscheidt, Rudolph Kunz, Cees VanDongen, and spare Claude Vigreux, who was needed when Kunz chrashed during practice. The bikes had special fairings and the dual carb GP- engine was optimised for high speed. They went home with 8 new records, some of them beating both 50 and 75cc records. |

1965Three more records were broken in april 65 at the straight of Hochenheim. For these records demanding a standing start, a 47 kg lightweight was assembled and driven by tiny Anscheidt. Result: 1000m- standing start was covered in 32,58 sec. an average of 110,49. |

There were of course other manufacturers who wanted a piece of the pie, and one of them was German Zündapp. During 1965 they built a special record breaker (see pics Zundapp1 and 2) and although the weather at Monza was not very good (why are so many record attempts so often plagued by bad weather?) during 12, 13, 14 and 15 May 1965, riders Andreas Brandl, Volker Kramer, Peter Eser, Günter Sengfelder, Heinrich Rosenbuch and Alfred Lehner broke the existing records. |
 |
 |
 |
The new records were as follows. 10 km : 153.452 km/h (old: 151.00 km/h) classes 50 and 75 cc 100 km : 162.002 km/h (old: 158.67 km/h) classes 50 and 75 cc 1000 km: 146.639 km/h (old: 117.02 km/h) classes 50 and 75 cc 1 hour : 162.609 km/h (old: 159.11 km/h) classes 50 and 75 cc 6 hours : 147.798 km/h (old: 139.49 km/h) classes 50 and 75 cc 12 hours: 137.039 km/h (old: 113.46 km/h) class 50 cc (old: 114.00 km/h) class 75 cc (old: 114.00 km/h) class 100 cc (old: 133.00 km/h) class 125 cc |

The engine was air cooled, and was developed from the trials bike, but was equipped with a rotating inlet disc and a five-speed gearbox, with an extra two-speed box behind it, operated from the left clip-on, just like the Kreidler racers, giving 10 speeds in total. Bore and stroke were 40 x 39.5 mm. Power was given as over 10 bhp at 11,000 rpm. Petrol with an octane number of 98 was used and lubrication oil was mixed with the petrol 1 : 25. The 18" wheels carried tyres specially made by Metzeler, which lasted the whole distance. Total weight was 82 kg.
On 14 May Volker Kramer broke the records over 1 hour and 100 km. The engine used for this had water cooling and was slightly more powerful (500 rpm more). The fairing was closed for better streamlining - the radiator was cooled with a little, battery driven fan. Using the same engine, on 15 May Volker Kramer broke the record over 10 km.

Utah, october 65 Learning from NSU, Kreidler returned with a very aerodynamic shaped vehicle, powered by a supercharged version of their dual- discvalved engine. Driver Rudolf Kunz piloted the Vaifro Meo designed streamliner to eight new records at the Bonneville salt flats. The supercharged engine received a new handfull of ice, into the cylinder and head cooling cavity, before each take off. |

1967In 1967 Signore Minarelli hired Otello Buscherini to drive their record- special, a membrane controlled 2- stroke with 4- speeds. Buscherini, weighing just 48 kg, did beat Kreidlers record from 1965, covering the quartermile in just 18:80:50, trapspeed 77,022 km/h. |

| On Sept 19th 1967 Kreidler tried to get back the 6 hr record with a now red coloured bike driven by Jan deVries and Rudolph Kunz. Due to bad weather the attempt to regain the long distance records failed. |  |
1968The annual sprint meeting held at the Elvington airfield, did attract 50cc racers too. In 68 the Van Veen brought their latest sprinter hoping to break several records. They did! Aalt Toersen broke three records : The standing 1/4 were done in 15,568s at 57,8mph. Standing kilometer : 30,318s at 73,8mph. And standing mile : 44,39s at 81mph. The bike shown with swingarm front- suspension were used for initial test on Zandvoort circuit |

1977In 77 Henk vanKessel drove the Piet Plompen built Black arrow down a straight in Apeldoorn, and nearly broke Kreidlers 1000m speedrecord.   |

1980Jan Nijhuys took a record in 1980, the standing- start 1/4 mile with this bike called Casal Sparta Plompen. Quarter mile was covered in 15,26 seconds and record speed after 402m where 94.29km/h. |
|
 |
 |
1981The Dutch finally got their record with this HuvoCasal driven by Jan Huberts to 224 km/h.  |

The Casal-Plompen world record breaker, as you can see it probably has the same engine as the Sparta, except this one used a Kreidler cylinder.
So the whole thing has technically nothing to do with Casal, i understood that rider Jan Huberts got money from Casal in Portugal to beat the 50cc world record.
Jan had a bussines named HuVo (Huberts-Voskamp), who builds the HuVo-Casal productionracers, Piet Plompen and his team builds the "cigaar" (for money !! )
Jaap Voskamp worked before for Van Veen as you will know. So you can see, the record goes to where the money comes from (with a Kreidler cylinder, HiHo, and more ? ) T. Kooyman 2007 |

| The Casal Plompen now resides in the Lexmond Motormuseum - Go visit ! |
 |
And of course, the record hunt never stops. The myriads of different classes in LSR- racing are from time to time visited by 50cc machinery. Some of them will be described here |
|
| Enter John Buddenbaums Minarelli AM6 powered streamliner! John Buddenbaum has set his sight on the 50cc topspeed record and broke it big time ! With current setup, a turbocharged AM6 engine fed by methanol, the Buddfab streamliner managed a speed of 233,3km/h! |
