Hi everyone I have recently brought a ty250a to refurb and register but I think the frame has been altered as the side panel and exhaust shield doesn't quite fit properly. 

Is there any reason for this to be done? 

Are there any standard frames to change to or any help will be great. 

Here's a Couple of pictures to explain what I mean 

Yes the rear frame upright has been moved forwards at the top end. Was probably done when the top shock mount was relocated further forwards.

Hard to tell from your photos, but the seat rails may have been lowered too.

Moving the top shock mount forwards and/or down increases rear wheel suspension travel.

Lowering the seat rails improves mass centralisation and gives the rider more room to move.

Looks like they have shortened the main exhaust chamber to fit the reduced space from moving the upright forwards.

Yes there will be standard frames about.

Thanks for your reply. 

Is this a common practice to be done then? 

Also are there any aftermarket parts that will fit it now like and exhaust or seat and side panels etc

You have a custom bike which means that aftermarket parts are not designed to fit it.

If you do decent photos of the RH side with the heat shield removed, people might be able to help determine if a WES main chamber will fit. You haven't shown the header pipe so can't tell what has been done there.

Side panels - no.

Can't tell about the seat either without good photos of what it looks like underneath. It may be the correct seat on it already.

TY frames are often modified but the way yours has been done is not common.

I will try and take some photos later on. 

Are all the twinshock frames the same if I can find one? 

This is a 434 frame will a 493 be the same  and fit everything correctly ? 

434 (A model) and early 493 (B model) seat bolts to the inside ends of the shockie mounts. 493 (CDE models) seat bolts to small additional brackets on frame.

CDE seat is different to AB

CDE rear guard goes with CDE seat. AB seat goes with AB rear guard.

434 has stand mount near left footpeg. 493 has stand mount on RH side of swingarm.

493 has threaded holes in the ends of the cross member under the motor (for the accessory trail riding footpeg kit)

Frames otherwise the same.

434 and 493 swingarms are different structurally but have the same overall dimensions and are interchangable. Early 493 (B model) has 434 swingarm structure with stand on RH arm.

Motors are different inside but interchangable.

If you have concerns about specific bits fitting just ask

 

I'm just considering a frame swap so I have a standard one on the bike and not the modified one. 

There is a 493 frame that's for sale that's why I ask about that frame. 

Do you know of any frames available anywhere? 

this is the frame that I've found would this be ok swapping everything over onto it? 

Its 493-200 also does it look intact

thanks for all your help 

 

my bike bIke in top picture then frame 

What is visible looks original. Can't tell if it is straight from that photo and can't see LH footpeg area

Have you seen the A model frame on eBay, looks okay in the photos 

Yeah I've seen the a model it's missing a engine bracket though
