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.

[Coyote]

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.

[FlyingDutchMan]

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 :no: .

This link should provide you with lots of useful info: http://easyweb.easynet.co.uk/~chrish/t-anodis.htm

[riffer]

It's an aluminium frame fella.

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

and here's a site (http://cr-x.org/cbr250/forum/topic.asp?TOPIC_ID=18523) 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.

[Roadrash]

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

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)

[F5 Dave]

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.

[Coyote]

Cheers for the info :niceone:

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

[Coyote]

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 :yes:

[Rainbow Wizard]

No we do steel and Zintech (steel with zinc pressed in) at work.
An anodiser said yesterday that he couldn't anodise my ali clad mufflers unless I removed the ali portion from the stainless steel.
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).

[Rainbow Wizard]

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.

[Blakamin]

Just polish it!!!

[k14]

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.

[Roadrash]

guess i walked into that one, bugger

Yeah, that was going to be the deciding factor.

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

[Coyote]

Who's bike is that? And where did he get his engine anodised?

[Blakamin]

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 :niceone:
you'd love their streetfighter collection...

[**R1**]

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 :bleh:

[k14]

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.

[SPORK]

Just polish it!!!
That's what I told him! I even made a photoshop to see what it would look like...

Errgh, sorry for the enormous picture folks...

The guy would've had to dismantle the engine to paint it wouldn't he? It would be too difficult to mask would it?

Streetfighter collection? :yeah: Gotta see that

Haven't tried wheelies on it yet, haven't had the space to practice. I tried a few stoppies, first time I came about 1 foot off the ground, second time, nearly toppled over :p

You can buy all that stuff here (often sold on TradeMe) and probably cheaper'n in the link you posted.

I'll have to look out for them then. Where else can you find this sort of stuff?

[F5 Dave]

Just to put a damper on things: Stripping a frame down suitable to anodise or paint is a huge task including all the relevant headset bearings etc which have to be replaced when moved. During powder-coating or painting all the areas like bearing holes & threads need to be masked up. In either process any earth points will need to be bared back.

Basically it isn’t worth it when you look at the expense & the time & well the bike ‘only’ being a 250 if you’ll excuse the slur.

Keep saving the dollars & buy decent riding gear & when the licence allows you may have saved enough for an R6/CBR/ whatever.

I guess thats what I'll do. I'll save up for a good jacket

[TwoSeven]

As far as I know the frame is made of mag alloy so probably wont anodise. The swingarm should, but without some kind of treatment on after will perish quickly, although many people polish the frames on those bikes - they come up ok if done right.

[Coyote]

I'll be working with Fibreglass next year at metalwork, so I could make my own fairings and paint them. I'll posts some pics when I get around to doing it

[Blakamin]

That gixxer was the dry clutch model so he made a custom cover... other than that he drained the oil, pulled the covers off, painted them, put them on and refilled the oil....
There's a couipla more gixers and a cagiva.... :shifty: and there is a rumour that the painter is doing some famous NZ racers bikes... but you didnt hear it here..... (the fact the bloke (who may of won a TT) and the painter were discussing it at the show has no bearing on this rumour either)

[Syphon_Life]

Ive done a full polish on my cbr250rr frame and swingarm, top yoke
and after 2 weeks or so i give it a good polish to keep it shiny,
ive never heard of someone anodising the frame but powder coating is an option like the new 04 r1
looks sexy,

Heres a pic
or half polished, half powdercoated!

in case if you havent discovered this forum yet it is awsome!
http://www.cr-x.org/cbr250/forum/

[Syphon_Life]

wheelies are hard on this bike you need real good balance,
the back tail fairing on these bikes are so frail and crack easily,
jumping pedestrian crossing are more fun i think!

oh heres a pic of my bike...

Its surprising how close the cibby 250 frame is to the cibby 600 frame.

Oh, b4 anyone asks - It got lifted down.

http://203.79.122.87/motorcycle/Assets/cbr600_pics/race_bikeA_thumb.jpg

I had mine blasted and powder coated (gloss for wheels, matt for frame). Engine I just cleaned really well and hit it with the engine enamel in a can, since its under a fairing - doesnt really need to be done too fancy (at the moment).

[Coyote]

How much did the powder coating cost? And was it too hard to dismantle the bike to get to the frame then put it back together, or did you have someone else do it?

[Coyote]

Probebly powdercoat the rims and swingarm aswell, so long as it's not too difficult. The rims need another coat on them

[loosebruce]

I bloody well hope so otherwise im wasting my time. As for crashing easier, well i hope not, but it should make it cheaper. :yes:
