What metal is a CBR250RR Frame made of?

Cheers for the info

Now for the most important questions, how do I re-assemble the bike after I've taken it to peices and anodised the frame, and what colour?

Dad might let me practice dismantling-put together the old parts TL125

Unless it isn't that hard to do myself, I'll take the frame to a specialist. Anyway, I doubt I'll be able to get hold of the chemicals needed.

It would be cool if I got the equipment to anodise anything I want however

This is the second time this week that I've heard of anodising steel, tell us more: in fancy colours?
What I do know is you cannot anodise ali CASTINGS, supposedly because of the silica in them (they just go dull grey and crappy looking).

Apparently it's a hard ceramic coating that runs rings around standard powdercoating, lots of great colours available. Probably a higher temperature fusing though so further investigation is required.
I want to do le Voxan's combination swingarm/footrest/muffler brackets that are cast and bead blasted, trouble is they always look dirty from road grime and boot contact so a smoother cleaner finish is coming their way for sure.

If you look on the cbr250 site that celticno6 posted earlier in the thread you will find that a member on there (Muzzy) has recently had his whole frame powdercoated black.

IMO its a waste of time. It will take ages to take everything off (you have to strip everything off the bike), and there are alot of things that can go wrong.

As to the question of how you put it back together. Well the answer is the way you took it apart backwards.

just like steel is a mix of iron an' shit (no, not literal shit)

Yeah, that was going to be the deciding factor.

Anyway, how much is anodising? And isn't powdercoating expensive?

suprisingly its not anodised... PPG candy paint.. been on it for a coupla years without even chipping... cheaper than anodising... the owner is a local and I also have the painters number

you'd love their streetfighter collection...

**R1** · 19th January 2005, 20:30

isnt the idea of building a street fighter so you can wheelie stoppy and crash easier?? my mate built one out of a old school gsxr750...it wheelied ok b4 he did it but man was that thing fun after with the higher bars and no plastics...do cbr250's wheelie? i know they do meeaan stoppies

They can if you rev the shit out of them and then drop the clutch. You have to practice though (i'm not game enough to try). I have a vid of someone doing one and it was a damn good effort. Not sure if you can do it for further than first though.
