Hiya

Been looking at this site for a couple of years now and thought it was time to join in,last June near Orleon in France i rode my 05 1200gs into the back of a car at about 40mph and snapped the top yoke,bent a stanchion and bent the small section of frame that goes from engine and supports the top of the front shock and the top yoke.Also broke my arm.

Bmw assist had me back in my house 6hrs later and my bike back 10days later.

Insurance wrote it off as a class "c" and i bought it back of them and repaired it.

It only looked like the stanchion and top yoke,until started the rebuild and discovered the frame section was bent,anyway its made of steel and i like a challenge and decided to build a jig and straighten it.

it was a bit involved because of the pressing for the top shock mount was in the way and i had to fabricate a former to go over this and onto the tubes ware they were bent. also had to support it from below because of the bolt connections sticking out.

anyway after an afternoon pushing it in the jig and a tiny amount of heat i got it as good as new ( bought a new one to take references from and took it back when i was satisfied i had repaired the damaged one) saving myself 400quid!:thumb2

The clocks were also F***ed ware the stanchion had broke free with the snapped yoke and hit the lcd display and cracked this,i managed to find a damaged 04 1200gs in a car breaker with damage to the clock housing and nothing else.so i bought the clocks for £100 and made a good set up after putting a new perspex screen in front of the lcd sreen on the original damaged set! bit tricky but you would never know it had been replaced!,saved about 250 quid on that.:thumb2

Nice metallic dark green tank and tail piece and metallic grey wheels and its better than new.:clap

Its rides straight and true and is just that little bit different from the rest.

You might see me around the south wales biker haunts.:beerjug:

So is the front sections not made for heat treated tubing? I would have thought it was.

I have a background in push bikes and everything is heat treated nowadays :nenau

Why not keep an eye on the welsh section Bluebird, come and join us at the abercrave in a couple of weeks. You'll enjoy the company and have a good ride out too :thumb

Maybe meet you there some day, Val.
 
Dont know exactly what kind of steel the front frame is but i did have the whole thing ultrasonic tested by one off the welding inspectors at work just coz it was free really:D
 
Blue Bird, with skills like that you sound like a good friend to have!

Colour scheme sounds interesting. Got any pics you can post?
 
ride out on Friday

Hi Bluebird,
You might see a whole lot of us coming through Abergav as usual on friday, so if you're about. Cheers
 
If you were going to such trouble, it may have been worth adding a few strengthening gussets to the stock frame in the headstock area. Why not improve on what BMW have already produced ??
 
Most steel bike frames (aprt from from ducatis) are just mild steel - cheap to buy and manufacture, easy to bend but easy to straighten
Is that the first written off / repaired 1200? - guess not but I've not seen a streetfightered one yet.....

Thats what i thought Phil,but the thing that really made me do it was the challenge coz it was well awkward.

As for extra gusseting etc if your gona bin it i think you want something to absorb the crash:blast forces and not transmit them through to the engine etc which would be terminal.

As for streetfightered,i did'nt have a mark on any panels at all.

Scraped the crash bars and screen and broke the righthand lever guard.

Painted the crash bars grey to match the wheels and polished out the gouge in the screen.
