once upon a time on european Grass and Sandtracks.....

Post by beat » Sun Jun 26, 2011 8:54 pm

hi al,
as I sayd, I have found a carton box full of Pictures ( around 200 ), al relaited to the thema Vintage MX and Vintage Grasstrack and Sandtrack Racing. Pictures are out of the years 1967 to 1977, I guess they have been collected by my brother Willy, and I hope some of them will entertain the one ore the other of you....

starting with the oldest one, it shows me and a next door neighbor`s son in the sidecar. -- so, beat was ad this time sweet 14 years ( yes Minety, <979 ) when he owned his first self modified Grasstracker. - a Sunbeam S7, where hi has fitted a Steib Sidecar on and replaced the "Gondola" by a wooden board....
Sunbeam 1967.jpg
first side, 500cc Sunbeam S7
so this was in 1967, the bike was doing a real " Metamorphose" within the next two years as to see now....
in 1969, the one on the left. - Sidecar modified for MX, - Engine replaced by the one of a Automobile, the DKW Junior, ( Auto Union ). 750cc, 3 Zylinders, Watercooled and 34 HP ! - Rider: beat, Passenger, Willy .
für Sitterd1969.jpg
two bikes ready for the very first race. a Grasstrack "Swiss Style "
the bike on the right, a BSA Gold Star, owned and driven by my Brother, Passenger: beat
fürSitterd.1969.jpg
two bikes, - one race, and none finished the 15 laps a race was counting!!
the only ( usuable ) Pic from this day :

after this "experiance", I decidet to build my first total selfmade bike, using the same engine from this DKW cars.
after a nearly two years time of bulding, the bike was just finished and presented on a Handy Craft Show of the Vally, where it winnes his only first price :laugh :laugh :laugh
1.selfmade DKW.jpg
first selfmade sidecar bike ( around 1971 ). DKW Two Stroke 3 Zyl. 750 cc Water Cooled
the decicion to use this Car engine again was totaly wrong as I can say now, because by tuning the Zyl.block and the pistons, - the Flywheel was failing cause of compleately overloadet by the Revolutions the engine has done now !!
originaly was 7400 Rpm in the car, - in the bike, - more then 10 000, - it explodet after a very short running time once by the other.... :cry: :cry:

within this time, I owned my first and only real MX solo bike :
GreevesGriff1970.jpg
Brithis Greeves Griffin, 250 cc
it was the one with the Swing arm fork and the short megafone exhaust. :grin:
but I realised: solo is not my busines, I need a third wheel on my bike.
so we vent back to this one:
Sitterdorf1969.jpg
the Goldy,
I modified it back for MX use, did one MX race with and then replaced the engine by a K*wasak* H2 750 two stroke.
( no usuable Picture out of this Time...)
as this engine was good and powerfull, but the Fraim was to short, we orderet a Wasp by Rint Tut.
750Wasp.jpg
brand new bike now,
K750Wasp.jpg
from now on, the results on the end of the race days where beter, and the fun by riding the thing was great as well......
750MX.jpg
the Wasp in action...
so far for today,-- continouse...

Thinking about it though, what was Beat doing riding a Greeves Griffon (with Banana Forks - that's two unnatural acts rolled into one) rather than a BSA? :shock:

Tom,
It's a rite of passage thing. If you haven't ridden an early Greeves you can't really appreciate something with valves.
Incidentally I believe that's a Hawkstone not a Griffon and the forks are straight leg leading link forks not bananas.
I've not got over the 2 stroke thing yet and have a collection of both Greeves and BSAs.

hi al, ...... continouse.....
Wohlen 1973.jpg
the Wasp with the 750 H2 Kawa in was a good bike, just the rear Swing Arm was a bit to weak, ( geting bend after a few races ).
the engine was enormiuse " nervouse ", but with 74 HP a strong instrument.
1973.jpg
MX Kawa 3 Zyl H2-750
using it for two seasons, the last one in the international class mainly in Switzerland, but also in Germany, France, Austria, Itali and Spain, - there have been a vew days where we had some Flowers in our Hands ad the end of the Raceday.
Bure 1973.jpg
but we had to realise one more thing : - most of our Flowers we have earned by the swiss style Flattrack racings !
ore clearly to say : me and my brother, we both were physikaly not strong enough for the MX sport ! - so, on most MX races, we could go with the fastest teams up from the starting line for let say thre ore four Laps, but then we had to reduce speed and endet up somewhere betwen Place 5 to 10 :(

by the end of the season 73 ( ore was it 74 ?? - aniway ) we decidet to stop MX racing and go for International Flattrack racings only.
they had different Tracks and different rules as well, so no Race was held in our country - and there bikes where different two !!

so, continouse.....

hi al, ....continouse.....
ad 1975, in central europe, there existing two classes for sidecars, - the 750 ccm and the 500 ccm.
the big ones had abouth a half a docent racings a year, the 500cc meet abouth 20 times a year.
so, as first , we built a new sidecar on to the Wasp MX Fraim to enter the 750 class.
soon as finished this bike, we started to build a compleately new one, using a K*wasak* H1 R A ex works racing engine.....

some pics of the 750 H 2 :
750Umbau.jpg
new side on the MX Wasp Frame for Grasstracks 1976
750kawMemming.jpg
stil a " high Goaz" on the flat field...
the engine was stil running on ordenary fuel, the side was a good design, but the MX Fraim was not a perfect thing for this situation...
750H2Kawa Grasstrack.jpg
as the Fraims design, it was hard to get this bike in to a nice drift.....
so, it was a " hard Bread " to competit with this special made bikes the Germans used, powered by engines like the H*nda Four, the M V Augusta four , the Tryump Weslake ore the Münch Mammut , al running on Methyl Alcohol...
750grastrack.jpg
" take it on the outside ! "
but stil, on several ends of the racedays we had Flowers in our Hands because it was the "right " sport for us :grin:

continouse....
as I sayd, in 1975 we started to build a total new sidecar bike for the 500 cc Grasstrack and Sandtrack class.
the engines the others mainly used where the 4 zyl. König small boat engine, a watercooled boxer with Rotary Valve and around 90Hp.
some Goddens, Weslake, Japs and Jawas singles where used as well, and a first 4 Zyl Y*maha roadracing engine and a first S*zuki RG 500 was coming two.
so our Kawa H1RA with around 80HP was not a Top shot, but stil able to catch them.

1975, building a new bike for the 500cc class
from left: my father, stil asking " dos this not bracke ? ", then FREDDI, nikname " BINGI ", my best Frend and a superb Locksmith and Pipefitter, then me, and on the right a " time consuming Guest " witch we don`t like to see them in our garage.....
after a four Month time of building, ( always ad nighttime, because we both where working 9 Hrs a day in a Factory ), the Fraim was done and vent to the Nikel Platting, and 3 more month the bike was nearly finished....
fast fertig.jpg
nearly done, just some saddlery work and other smal things left over....
5003new.jpg
first time out
as we had a lot of experience from the 750 H2 Kawa abouth tuning it, it was shorter for us to build this one , mainly abouth the design of the Exhausts, because this Two Stroke is very sensitive abouth the mesurements of the Exhaust pipes......
5003firsttime out.jpg
first time out,- ready for testruns.
isn`t it something beautefull such a brand new bike ??? :grin:


first runns on some flat feelds and one day testing it on a Sandtrack in Germany was showing: yes, it will do it !!

hi al,
continue....
after a race ore two, the bike was realy finished, al the lidle ods have been nicely made as " beat`s Style " and it was looking like this:
in Kiel Germ.jpg
the chair, ready to go fast ! ad Kiel in Germ.
the Kawa H1RA 500

and as to see, - a very different Bike compared to the high Goaz the 750 was...
750Kaw3forFlatt.jpg
the H2 for Flattrack
on this 500cc, there was just one litle fault stoppig us from " enjoying the Raceday " : the second Race we did , the Crankshaft explodet by damidged Bigend Bearings.... :cry:
as this engine reved up to 13 000, we know, we have not overloadet it on this point, no.
we realised a other thing : the Trust Washers wich are located on each side of the Bigend, guiding the Conrod in the achsial direction ( to the left and to the right side of the Crankshaft ) was overheated on the right side only and the Bigend was overheated as well !
the Thrust Washers where made out of Bronce, coated with Silver, a smal, fine thing, - no space to replace it by a Trust bearing...
and clearly was to see, ONLY THE RIGHT SIDE WAS THE PROBLEM !
so, this Crankshaft was not able to cop with the zentrifugal Forces coming up in a Sidecar use in the long courves to the left !.....SH*ç"°§$ :!:
by luck we meet a Sidecar Roadracing Team wich has had the same Problem just a Time before. And they got the Solution: guiding the Conrod upside in the Piston at the Pin, and let the Bigend Side float by totaly abouth 5 mm !!
A excelent Workshop in the country did this job for us as well as for this other race team, and from there on the crankshaft stays up to 7 ore 9 racedays before it bangs agayn by abused bigend bearings. ( to much Play in radial )
some pictures to enjoy....

hi Ian,
Ian Hingley wrote:only scratched the surface
you have got it very right, - there was a lot more within this ten years, I also bought my Cheney from the same guy as we had the Wasp Sidecar from him in the year 1973.

and the BSA and my demand of " seeing a bit more from this World " was one of the reasons why we stoped Motorsporting.

Motorsport isn`t totaly banned in Switzerland, no, just circular racings for cars and motorbikes on bitumen surfaced roads, it is. ( the classic Roadracings )

Beat, I'm totally blown away with these pictures, and I'm going to go back through them at my leisure :smile: :-
One thing I definitely share is passengering a 3 Cylinder DKW engined sidecar, it was called 'The Banshee'...it needed a 12 speed gearbox to keep it in the power band!!! not a crappy 5 speed Albion like we had!
we later put a 754 BSA (A65 with A10 crank) in it, and finally a Hillman imp car engine.
We were sponsored by our employers Eutectic Castolin, who were based in Lausanne..so ther was a Swiss connection too ;-)
Please keep your pictures and recollections coming

hi giles,
yes, this smal DKW car engines where used for many things, there sound was impressing and it was enormius what a HP was able to get out by other exhaust pipes and other carburators used. ( and some Windows modifications on the pistons )

about Eutectic Castoline : we used the Silversolder and there Flux for doing our Fraims. and I know, I was warned to use this Stuff only in good ventilated Rooms. but as it was almost wintertime and nighttime when soldering, our garage wasn`t ventilated.
so now, 35 years later, al my Boons are still in place, none is holding together with some nails ore screws. the ones they get in to two pices by some litle happenings on the MX tracks are grown together naturaly. just one " remembrence " I have to cop with, it is the Lung. - Castoline and Silversolder is sending me some late greetings more and more, mainly during wintertime !
BTW, good picture of your Sidecar roadracer !!

in " overdrift " on Grass
hi al,
just bringing this three pictures ( the last ones :lol: ) up to explain something. ( maybe from interest for the one ore the other...)

as one of the Keys to be fast on the Track is the STYLE you can let the bike go in the corners.
wich means, also a sidecar bike has to slide something similar as a Speedway solo bike.
for this reason, the line of the sidecar wheel is adjusted NOT in a parallel to the front and the rear wheel line of the bike! no, it lines hardly to the right side of the Track, and wheilst the al bike is drifting in the corner, the sidecar wheel should aline with the direction the Track is going!

ad Picture 1, the thing is going to slow, - no drift ad al! bad :(

ad Picture 2, nice speed, good drift, sidecar wheel alines to the Track. :grin:

ad Picture 3, - a especial situation : the bike is to fast in the corner, the al thing is sliding to much, the sidecar wheel indicates clearly no alining to the Track, it works like a Brake !
the frontwheel is set close to full " contersteering " to keep the direction of the Track for the al bike . the thing is nearly helplessly " overdrifted ".
and, within the next half a second , it will " kicking back " as we used to say. ( something similar to a roadrace bike when it is doing a " highsider " - get the Wheels back in one line )
to get a sidecar out of this situation, it needs mainly three things: good nervs of the riders, - a very sensitive right Hand for just closing Throttle the right litle bit - and a very nicely and fine tuned engine wich reacts crispy :!:
( no, the Foxtails didn`t help ad al ad this Time.... :laugh :laugh )

how ever, we have had al this things ad this race, and now, many many years later, we can have a smile on the face as well.....

beat :mrgreen: :mrgreen:

beat, I'm right with you with your descriptions of pictures 1, 2, and 3, and solo or sidecar...
But NUMBER 3 does it for me :ban !!!!!!!!

Now the class is restricted to single cylinder speedway engines, they probably have less power than you had from your Kawa 500
Maybe a little more manageable though :smile:
thanks again for the brilliant pictures
giles
