What metal is a CBR250RR Frame made of?

[Coyote]

I want to turn the CBR into a streetfighter, and an anodised parts i.e brake levers and frame, would be awesome (if it isn't too much, if it is, I'm scrapping the idea). Is the MC22's frame made out of Aluminium or not?

made of cheese aint they?? or was it instant pudding(yum)
not that it matters you can anodise most metals.

[Motu]

Dunno - I don't have the data here...but I'm pretty sure they were Lion Red cans,rather than the more up spec Speights can composition....

I thought you could only anodise Aluminium :spudwhat:

[Blakamin]

frame is alloy......

[vifferman]

frame is alloy......

Yes, yes - we'd already established that.
It's an alloy of cheese, pudding, and Lion Red cans.

Anodiseable?

[Blakamin]

Yes, yes - we'd already established that.

thats the one!!!!! explains the flexibility

No we do steel and Zintech(steel with zink pressed in) at work, your frame should be aluminium, but with a Honda who knows they have done all sorts of funny things over the years.

I'm pretty sure its all Aluminium. You can try anodising, which I wouldn't do myself (involves lots of sulphuric acid and lots of electricity by my understanting). Your best bet to my mind is to get it powder coated - this doesn't effect the strength (anodising does), can be semi-easily removed (unlike anodising) and is quite hard wearing. You just can't polish it the same way though .

It's an aluminium frame fella.

here's some more info on your bike you might find useful.

and here's a site where they talk about changing bodywork to RC211V

Ah... that's not actually true.
Powder coating requires the paint powder to be baked on, which can affect the strength of some aluminium alloys.

i think its "ali"(an alloy is any metal that is mixed with one or more other types of metal).

exactly.... the frame is alloy... aluminium alloy yes, but still an alloy... if it was straight aluminium, theres a damn good chance it would fall apart..
just like steel is a mix of iron an' shit (no, not literal shit)

Jury is out on the powder coating, depends on what temp it bakes at & what type of ally the frame is as to whether the temp will affect it. (Work hardening or temp)

With anodising some allys take to it well & others don’t anodise very nicely at all. General rule of thumb is cast ally doesn’t anodise well (headstock & sw pivot are likely cast sections. New Hi-tech Hi-pressure casting methods employed on last couple of years Jap bikes seem to have gotten around this.

Forged wheels can be anodised (RSV factory etc) but cast ones can’t.
