The 50cc Bultaco began as the project of two Dutch enthusiasts, as a Piovaticci.

Text and pictures Courtesy of http://elsberg-tuning.dk/1975.html, a very good site:

"When Jan Thiel and Martin Mijwaart dropped the Jamathi and moved to Piovaticci, at last they got some money for building racing motorcycles, instead of paying for everything themselves. The new bike of course looked a lot like the old Jamathi, with a stainless steel monocoque frame and the one Koni rear shock absorber, Ceriani front forks and cast wheels by Ringhini. Tyre sizes 2.00-18 front, 2.25-18 rear. Also reminiscent of the Jamathi was the engine with the horizontal cylinder (see Piovaticci2). Bore and stroke were 40 x 39 mm, for a capacity of 49.0 cc. Compression ratio 15 : 1, carburettor 28 mm Mikuni. Claimed power was 17 bhp at 16,000 rpm. This was no doubt a very modest claim - in practice the bikes were maybe even faster that the Van Veen Kreidler, and on several occasions Lazzarini was able to grab pole position. Picture Piovaticci3 shows Jan Thiel (foreground) and Martin Mijwaart working on the bike."

After that, they moved to Bultaco and Nieto won the title with it.

PS: there is en error in the text: the wheels were not made by Ringhini but by Campagnolo on a design by Morbidelli. However anyone could purchase these wheels and Campagnolo sold lots of them in both 2" X 18" (50cc size) and 2.75" X 18" (125cc size).

You can see some on my own ex-works Morbidelli 125cc currently in a museum in Los Angeles:

1963 pic of a new CR 110. I think this was raced by Charlie Mates who was a good 50's riders of the 1960's.

T54, there seems to be some confusing issues regarding MBA - Motori Benelli Armi and Morbidelli.
The bikes looks identical, maybe different engines?

Morbidelli had Joerg Muller design and engineer the 1975 to 1977 world championship-winning 125cc and 250cc bikes. Giancarlo Morbidelli then sold a licence to Benelli Armi to manufacture production racers based on the 3-transfers 36HP engines, with a copy of the works frames and parts. The resulting product was called Morbidelli-Benelli-Armi or MBA. But things went bad when one of the works mechanics defected to MBA with the factory secrets, and things went even worse when Muller and world champ Pier-Paolo Bianchi were suddenly fired and both joined MBA.

The ensuing war was not pretty, but from the basic 1977 MBA production racers (50cc and 125cc), every following MBA's were no longer a product of an affiliation.
Morbidelli had his revenge when MBA went bankrupt in the mid 1980's and he was able to acquire a pair of 125 and 250 MBA's for his museum as damages.

I arrived at Morbidelli in 1977 just at the time of this in-house disaster to fullfill a contract regarding a 250cc with advanced features. That new bike, built secretly in California and after hours at the... Kawasaki R&D facility and unbeknown of anyone there except one person, was developed and tested with Graziano Rossi as a driver. New aerodynamics, new frame with re-distribution of weight, new front-end with built-in anti-dive, fuel tank below and on front of the engine... all in all too many new things, so only part of them worked well. Once redesigned with a few more conventional items fitted, Rossi had a good bike, but the Kawasaki inline twins had more power, so Rossi won only three GP's but finished third in points to Ballington and Hansford, despite that Hansford had zero wins but was very consistent.
Problem is, at the time I had other things to do so I neglected the project once delivered and simply could not make it advance. My regret today.

I think that it is a copy of a Piovaticci/Bultaco but is not an actual Bultaco.

Well, that really was an inside story, so to speak, of the Morbidelli/ MBA relationship.

You are partly right, when assuming this Bultaco- Kreidler of Gerhard Singer is a copy.
The frame was made by Tavi, the Bultaco- mechanic of Ricardo Tormo in 1982.
A very nice bike.

It's Lee Allen on a Ducati, hopelessly out-powered by everyone. But he finished in the points and got... one.
#10 is Jean-Pierre Beltoise (Kreidler 12-speed). #1 is Hugh Anderson (Suzuki 8-speed). #7 is Tarqinio Provini (Kreidler 12-speed). #2 is Hans Ancheidt (Kreidler 12-speed). #5 is Isaoh Morishita (Suzuki 8-speed). #4 is Mitsuo Itoh (Suzuki 8-speed). #6 is Luigi Taveri (Suzuki 8-speed).
Now I feel like Doug Nye! :lol:

I compliment you Gentlemen, what an amazingly interesting thread. Now George Ashton, there's a name from the past. Was it he who raced apart from the Honda 50, a tuned road-engined Suzuki/Yamaha/Honda? I know it a bit vague but I can recall this tiny home-built special from the 1960s. Did Fred Launchbury, famous for his very fast Bantams, ride in 50s?

"Hopelessly outpowered by everyone" - the exact feeling i experience every time i enter my supercharged Honda against 15- 18hp Kreidlers :rotfl:

Could that Ducati be anything but a two- stroke sports moped?

Just to put some dates into the Jan Thiel/ Martin Mijwaart monocoque- racers:

1973: The first monocoque Jamathi

Posted Image

1975: The Piovaticci

Posted Image

1976: The Bultaco

Posted Image

1982: The Garelli

Posted Image

Jan Thiel just recently retired from Aprilia, leaving a big impression in the records:

"I was trying to beat Kreidler with first Bultaco and later Minarelli and Garelli until the most beautiful class, the 50cc, was abandoned, a great pity. After that I have worked for Garelli, Rumi, Derbi and Aprilia until I retired two weeks ago. The machines I worked on have won a total of 46 between riders- and constructors worldchampionships winning a total of 287 GP's in 50cc, 125cc and 250cc. But my best memories are about 50cc racing where you could achieve good results, even with modest means."

what a great thread :wave:
the 50cc class was surely the purest formula,
the challenge to get the last ounce of performance from just 50cc must be the ultimate engineering challenge...

i wonder what power output could be achieved using todays advanced materials and computerised tooling........ :blush:

i can still remember the fantastic display of Nieto's ex-race bikes at the first ever Motogp meeting at Valencia's Circuito Ricardo Tormo in 1999.

In a 67 long- distance race? George Ashton shared a Suzuki with Chris Walpole.
George Ashton made it big driving the Italian/Dutch Garelli. In 69 he won 32 races out of 35 entered!

No, the bike I'm thinking of was an extensively modified 50cc Japanese road bike, a special, tuned by Woolley, and raced successfully in the UK in the 1960s. I just can't think of the rider's name but it'll come to me. I just thought it was a marvel of engineering and enginuity. Clearly not Ashton then.

Kreidler did hire Taveri and Provini for the 64 season. Both drivers complained heavily of the cumbersome 12speed transmission, and Taveri later recalled the move to Kreidler as his worst decission ever!

Now I get it :o

You must of course be thinking of the Brian Wooley- built Yamaha. It was only in last October I saw this bike in the now- closed Motormuseum Lexmond, complete with its svingarm- mounted Gomatic two- speed reduction box.
Thus the (what was the designation of this Yamaha engine) 4- speed became an eight speed.

I believe the driver was Trevor Burgess?

I drove the Kreidler 12-speed loaned by the works to Claude Vigreux several times and I had no problem with the shifting of the 12 gears. True that Provini simply could not cope with it, and Luigi was not so keen about it either. But if you began life on a 3-speed Peugeot BB Sport as I did with the cable-actuated shifter on the left hand, then progressed to a 5-speed Derbi with the foot-shifter, you never had any such problem with the Kreidler! :lol:

Hello Guys,
Its definitely Hughie McIvor from Stalybridge,and he's an ulsterman originally,hence the logos.I know its him as I also raced a CR110 against him at Darley Moor.He was the last person to race a CR in the UK at least.The Woolley bike mentioned could be the Woolley-Bone special (Andy Bone Notts) Loosely based on an Itom but low and long not unlike the Garelli ridden by Stuart Aspin and George Ashton.George it was who rode the W-B special.

That's just as well because if indeed it was pretty, it was also very slow and handled like a wet noodle. Any bike fitted with a 3 or 4-speed Franco-Morini engine (and there were a plethora of those...) would clean its clock.
Of course if you had bought it and kept it, the Maserati freaks would pay you a king's ransom for it today... :lol:

Before I forget,yes Trevor B. rode the Woolley Yam,And then I think Mick Warne,but I no no idea about the transmission.There was a Garelli about around the same time with an 8(or possibly more)speed gearbox.The bike was quite'normal' looking not a GP lookalike as the Agrati-Garelli was.

What year did you race against Hughie McIvor ? Did you race other 50cc bikes than the Honda?

That's the 50cc MZ. It ran only a few times in 1963 because with only 11HP it was too slow.

Except pictured driver is Walther Brehme.
MZ didnt get a second chance to develop the fifty, because of an obligation made to the Simson factory.
MZ did motorbikes and Simson took care of the moped/scooter market.
A sad story really, I´m sure Walther Kaaden could have made something out of the fifty.

Just a guess, but the rider of the #19 machine could be Mike Simmonds, brother of Dave, so the bike could be a Tohatsu, although I have a feeling that before they played with Tohatsus they were Itom pedallers, and the megaphone exhaust would support this possibility. The lineup of the pushstart photo, with all the white pudding basins with black stripes, looks like a brochure for the All-German Roadrace Factory production line....

That´s cos it´s the old communist East Germany I would imagine, judging by the policeman´s uniform. There wasn´t a great variety of kit available in the local bike shop for those diehard racers, and the fans were just about the most enthusiastic this planet´s ever seen. They were grey times for the folk there, but they didn´t let politics interfer with their love of m/c racing.

Hi 50cc racer,
I raced the CR at Darley and Snetterton,in 72 I think.Before that I started on a Handa SS50 road bike,completely standard,and even rode it to the meetings with the mega exhaust slung rond my neck like a banjo!Last qualifier in my heat for a place in the UK 50cc championship round.In those days there were too many riders for just one 50 race at Darley,with a max of 24 riders on the grid.Great days.
The SS50 4 speed was a great bike but a bit too slow to keep up with most of the strokers,so I built a Garelli in my mums kitchen-bless her,with the Agrati race kit on it.£30 for a ported chrome lined barrel,cylinder head,carb(a baby Dellorto SS)and expansion box.It was only a 4 speed Monza road based bike so it to go.I had always lusted after a CR110,so eventually managed to get one.£250,yes 250,buts thats all they were worth then.

Nice bikes all of them, easy to drive and not to peaky. Any chance of pictures from your races?

The SS50 engine started its life in 65 and is still in production, and by that it must be the most produced 50cc engine ever! And the most copied too!
Its rather long stroke (41,4x38mm) relates to the fact, that it was born a 65cc (41,4x44) but I can tell you that it has no problem revving past 15000rpm! That doesnt make it a racing engine, considering its main disadvantage: a dry weight of 18kgs - thats seven more than a watercooled Kreidler- engine!
Sounds a lot better though ;)

Hi 50cc racer,
Sadly no photos of my 50cc racing days,all lost during times of marital strife!!I will try to dig out a photo of the CR when I first bought it.I had one last fling with a CR110 in 1986 when I rode a borrowed one at Donnington Park in a parade of CR racers.Quite a few CR93s on the track,but I was on the only 110 out there.
Funny you should mention the 65cc.I had one on the road,a 1965 model,in red of course,number HCH 650C,I learnt how to ride properly on that little bike.
Incidentally,Brian Crighton (of JPS Norton rotary fame) started his career on a C110 and then fitted his own tuned SS50 mototor to it.At twisty circuits he could run with the CR110s.I bought this motor from him,it could run with with a YAS1 125cc Yamaha on the road

Before my brain fades completely,the Honda CR110 that Hughie McIvor rode was probably not only the last CR to be raced in the UK,but the 1st also.I believe it was the Val Knapp Honda ridden in the 1963 TT by Ian Plumridge to 6th place at nearly 65mph average.Not bad for a bike with a top whack of only 85mph.It differed from the regular production CR110s most noticibly by having the contact breaker driven by the inlet cam on the left(like the works singles) and not by its own gear driven shaft on the right front of the crankcase.
Any other CR110 'trivia' would be greatly appreciated.
The Herr

I know that bike because it was me riding it! The frame was made by the Simmonds brothers and powered by an Itom engine. I purchased the complete bike from Dave. It was probably 1962 or '63, like most of us the memories not what it once was.

Herr Wankell:
Before my brain fades completely,the Honda CR110 that Hughie McIvor rode was probably not only the last CR to be raced in the UK,but the 1st also.I believe it was the Val Knapp Honda ridden in the 1963 TT by Ian Plumridge to 6th place at nearly 65mph average.Not bad for a bike with a top whack of only 85mph.It differed from the regular production CR110s most noticibly by having the contact breaker driven by the inlet cam on the left(like the works singles) and not by its own gear driven shaft on the right front of the crankcase.


There were other features to recognice.
The first batch of CR110´s to hit europe were 5-speeds, from there on 8-speeds were the rule.

Any other CR110 'trivia' would be greatly appreciated.

Hi Renzo,
I always thought that Val Knapp was an american(only because someone told me that).Know what you mean about the Benly.A lad used to come to our youth club in the 60s on one.It had long megga's on it.I used to ache with desire for that bike.His mate had a YAL1 100cc yamaha with expansion chambers,that he made at tech college.At the same time my brother had a 1960 swinging arm Scott 600.With that lot around there was no hope for me,and I'm still cursed with motorcyclitis.
