Cutting frame loop

[classified-moto]

Hi all

I'm 90% through my project brat style 125. I've got a nice brat style seat and have moved indicators and tail light etc and now have a large frame loop extending out with no use for it at all. I've attached a picture but my bike doesn't have this seat anymore so it's much more visible

My question is, is it safe for the frame structurally if I were to cut it where the arrow is pointing to? I haven't got the money to have a loop welded at the minute so wondered if I were to cut it for now would it damage the strength of the frame

Thanks for the help

Do you expect to get a MOT on this thing?
If so go read the SVA rules... modify the main structural member.. ie 'the frame' bike needs to be single-vehicle-approval, and re-registered.

What you are talking abut cutting BTW is the seat rails. Man backbone extends from the head-stock to the suspension mounts; rails around the engine are the 'engine cradle'.

Cut ANYTHING between the headstock and suspension mounts, you will certainly require SVA. abreviating the seat rails, you might just eek through regs, but READ THEM FIRST before you get the angry-grinder/hack-saw out! And yes, take outthe stay between the rails, the abreviated rails will need some-hoe bracing. Needn't be welded, if you are cunng a bolt-in cross member may be sufficient. But it will need bracing, especially if you have ditched anything else that might bridge & stiffen them like a steel mudguard.

I do ride it every day for work and a lot of careful attention has gone into it so not sure what the wanker style refers to but hey ho

Some people say cutting it won't make any difference to strength of frame and some say it definitely will do I don't know what to do. The loop just doesn't go with the look at all and looks ridiculous now the work has been done so if I could take it out that would be great

How would I brace it? What would I need?

Hi

I think you'll find that if you cut that off you'll need to put in a cross-brace for strength.

Anyway of doing it without welding

Thanks for all the really sensible and helpful replies

I think it's great the amount of assumptions you've made when you haven't even seen my bike and don't even know what kind it is and what modifications have been carried out but you carry on

I doubt it would have any serious effect and plenty of others have done similar things to the rear of a bike frame.
Welding a cross brace would be tidiest but in the meantime
you could close the loop with a bar and nuts/bolts

Or, just ignore it and cover it over/carry on regardless
as I expect it has some sort of cross member not too far from the shock top mounts anyway.


Show us the bike !

The problem with "Cafe racers" is not people building actual Cafe Racers. It's the Hipster shit purporting to be one, and is in reality a perfectly good bike that's been mangled into a style that does not suit. It's done badly and with no regard to safety, rideability or performance, it's looks over everything, and those are done with a large set of goggles on.

If you have the skill and taste to build an actual cafe racer (go do some research first), then you'll find most people will appreciate the build, even if it's not a thing they would do themselves. I can appreciate a well build chopper even though there's not a chance you'll find me on one.

'Streetfighters' get the same treatment... it's not usually a 'fighter, it's a race rep that someone binned and hasn't got the time, skill or wallet to bring back. Usually badly done, though not to the extant that Hipster bikes are, it's visually unpleasant, rather than fucking dangerous.

If you're modifying frames, get and learn to use properly, a fucking welder, and Rustoleum is your friend.

Yeah what he said
I love to tinker and mod, especially on my 'built from spares parts lying about' old thing that has little intrinsic value

I don't have an issue with folk having fun modding their bikes
but It has to be fit for purpose.
People who remove mudguards, turn the handle bars upside down
add paint and shiny bollox then expect shit loads of dosh for a cafe racer unfit for normal use boil my piss.

Presumably OP has flounced, or ended up in a ditch?

If not, then at a minimum, I'd run a length of threaded rod across and just bolt (well nut) it together until funds allow for messing it up properly.
