hi guys n gurls

well to start with hello to everyone im new on the forum and this is my first post lol

just wondering what suspension and brake ugrades there are for the RS125... im currently working on one (not sure of the model or year) and im hopefully putting a pegaso 650 lump in it and using it as a practice stunt bike. as the engines gonna be a little heavier and im gonna be liftin it up on one wheel alot i figured id need to upgrade the supsension aswel as the brakes. any help would be much appreciated

fitting ktm forks means youll need ktm wheels which in turn means you need a new speedo drive system as the rs speedo drive runs off the front wheel, not too mention you would need KTM brake callipers and discs, which in turn would probably need new master cylinders and levers, im not even sure if the ktm forks are 40 mm and will fit the rs yoke sso you may need a ktm top yoke and bott yoke



also ittl sit too high at the front as ktms are SM's



see why its silly now ?

best thing too do to the front suspension is use better thicker oil and/or fit an air valve on the right fork with 3 or 4 psi in the fork

also dropping them threw the yoke 10 mm helps produce a better angle of attack



as for the rear shock a sachs boge SP shock is what you want

or

a custom made maxton unit

thanks for all the help. ive spoke to a lad about some 250 forks and he's sure there 50mm and ive had a quick check of mine and they are 50mm so hopefully they will fit.

im not really too fussed how its going to look as its a low budget bike to practice on its gonna be bounced off the floor etc so cosmetics arent really vital.

i did look at the maxton shocks but they are big money from what ive seen. ive been looking at the 250 rear shocks and they look as if they will fit straight on.

thanks for all the help

Low budget? Surely fitting a new engine, forks, suspension, other parts that need replacing because of all the changes... Etc etc, will NOT be low budget?

And surely straining an RS frame with a 650 lump AND stunting isn't really the 'um... Best idea?

Would have thought it would be a lot cheaper to buy a used 600 stunter, or even just a cheap used 600?

not really as i can do all the work myself. the only thing ill hav to buy 'stunt wise' is the handbrake and clutch leaver an then sprockets and chain the rest can be dont myself e.g. cage, wheelie bar etc... as for the bike itself if i can pick up the shocks and breaks cheap enough its just a case of finding a donor to go in it then again all the modifications to the frame will be done myself. it will make ideal stunter as being a 650 single it'll have plenty of grunt in a light wieght frame

buying a 600 then stuntin it would be more expensive i've spoken to a few people about it and looked into it. im lookin at spending under a grand on this project. and to get a 600 and stunt it or to buy one stunted already ur lookin at 1500+

depends on your weight the haynes says 10 - 20 W oil

i use 15 W

i have heard of different weight oils being mixed to suit before now

if your gonna drop the forks id suggest use a heavier oil then 10 W
