Derestricting my TZR 250 3XV RS

[AndyYam]

Man that's a bummer  The frame is really delicate, if you look at how thin the main frame spar material is (by big holes on the side that show the thickness) - it's basically ally sheets welded together.. compare it with the NSR which I think uses extruded sections?

Either way I was suprised how light the frame was when held separately which made me wonder how easily it would bend.

The good news is that as the frame is so delicate & light then it'll not be big forces and aluminium ripping stresses to set it straight again. I just telling myself that and I'm sure those that disagree with me will have the sympathy not to point out otherwise   

Makes sense to me. Assuming you're still planning to get Moto liner to do it then you really don't need to worry much beyond having the cash to pay the bill. They've been renowned for this work and will have straightened out more bent frames on bikes that will have been crashed harder and then ridden harder than you plan to ride her.

In terms of safety if they don't think it's safe then I don't think they will do it. I've only ever heard great things about them.

I guess at that point it's a ballache of transplanting, moving the plate and re registering but that's only a small chance.

Your focus should be on getting a good stock of biscuits and finding a day that Thump you and I are all free to prep her for her operation.

By the way it looks like Gecko has a frame for sale that's already in the system it seems. Might be worth it for peace of mind etc?

Thanks all 

I'm going for the Motoliner route. I'll hang off on the frame as I'm getting tight on space.

I've had a long conversation with Motoliner and know what's needed to the nut, so I'm going to sort that and think about transportation and if I can get this done in a day for simplicity in that regard.

Down but not out (again).

I've had the same problem, bought a freshly powder coated frame as a project which turned out badly bent at headstock.
Motoliner wanted £450 plus depending on damage ( not inc vat) and I'm a long way from them.
I had a spare frame in the attic, half day on my own stripping it and a day with two of us it was complete and running again.
My problem was and still is getting the new frame registered! Takes ages.
As stated by others they do not seem very strong at all at the head set.
I'm going to try straighten it myself when I need it. Will post some pics.
Anyways good luck getting it sorted, these bikes ain't cheap.

Hey, Scotty.

I have a 3xv1, modded for track work. If your 3xv headstock seems weak, you're going to attempt an DIY on your current bike and you're not trying to retain a "showroom stock" appearance, have you considered adding aluminum plates to beef things up?

Bending aluminum requires extreme heat and can cause further weakening of the headstock. This is why I recommend reinforcing this critical area of your bike.

Good Luck.

The shiny frame is bent, the Matt one is fine.
You can see the bulge on side just above the lower weld.
Underneath there are punched holes no longer round and the rad mounts drop down.
Mounts should be in line with each other.
Not sure if Rich's damage is the same.
Motoliner use oxy acetylene in the straightening process hence all wiring etc had to be removed. They want the motor in though to make frame stronger during the process.

Interesting, it the metal behind the frame that's done. Mine looks ok to the eye, and the rad bolts are straight so I guess mines less bent than this and that's a hopeful sign for getting the experts on the case.

I still haven't started stripping the bike down, I will do, but it's lost it's priority

From what I recall USD forks tend to bend the frame first and standard forks bend the forks first.

Never thought of that. Interesting

I have less urgency and eggs in the single TZR basket.

I feel a bit more detached from the TZR repair now, less invested and all as a consequence - I'll be able to face it a bit better.

Did someone buy a Brazilian Rd?

Did someone buy a Brazilian Rd?

Nope, it's not the RD R, it's a Uk '91 F2

Thats the best type

After the crash I've not had much enthusiasm for my TZR, but here it goes. I will get this running again for summer (I hope)

See video - https://youtu.be/tgmh-XB0vAc?si=B7Ux7T5xOMfQWobH

The eagle eyed amongst you will notice the right hand upper engine bolt looks loose. I just went out to the garage and checked; it's not loose, it's snapped!!! Ahem, this bike....

[jamietzr250r]

Nice to see work being done.
Question
Have you phoned motor liner at all because I fear you need a completely bear frame...

My Christmas presents were a new Simpson venom helmet and blue RST boots (for the bike..).
