cb125 motor in cr125 chassis

[geraldo]

can anyone provide me with a copy of an article from (I think) Cycle magazine from (again I think ) about 1974 - 76 where they put a cb125 (or made XL125) motor into a cr125 rolling chassis - very vague I know but maybe someone will remember

wow these days a magazine changes the bars and stickers and they carry on like it is brain surgery. Those were the good ole days when magazines were as silly as the owners.

So what would be the modern equivalent article.... putting a Ducati 1098 engine into Aprilia SX chassis.

Alan Jones was racing an SL125 powered Elsinore back in the day and I believe he also raced it in the early years of vintage. I think he gave the bike to his neighbour with a stock SL motor and put the Yoshi SL in Ugly Betty his purple Metisse.

thanks for the photos KB171 , will help with the upcoming build , interesting to see the intake is routed outside of the frame

[ride red]

the intake pretty much has to go to the outside of the frame. the brake pedal and kickstarter are issues as well, but where theres a will theres a way .

Still the standard set up (Except the CR 125 forks that fit straight in the triples..) requires no piss farting around with intakes and controls. More money for good shockies

I thought the saying was "where theres a will theres a relative" 

[geraldo]

will probably start off with standard rolling chassis but the cr125 rolling chassis is MUCH lighter - therefore better power to weight ratio , thats why I am asking questions about putting the little 4 banger into elsinore chassis

[Tim754]

Hmm how much lighter I wonder? You may be very surprised at the difference in the bare frames with only forks and shockers and wheels fitted.
 By all means remove the SL's steel guards and cut off all the road going brackets , add a set of CR125 forks (That are heavier than the SL's standard ones !) a good pair of rear shockers and CR125 wheels (fit very easily just adjust spacers). leave the standard tank and mull over what to do with the fat arsed standard seat, which on mine I leave...  Resulting difference in weight between the two rollers is roughly 2.7 kilograms... the biggest weight difference is the four stroke single overhead camshaft lump as opposed to the trim little Cr125 two stroker.
Friend I have done what you would like to do, and well it was great fun! but in reality not really any difference except I rooted a perfectly good CR125 frame. Sadly that rolling frame less engine was totally obliterated in a shed fire here, worst part was the wheels ,tank ,seat, guards and sidecovers were fitted.  Cheers enjoy the challenge

thanks Tim , will take another look at the sl frame
