on my last trip.  I was surprised/disappointed by the stability in the sand.  the 250 ttr is a short motorcycle.  I decided to fit a steering damper and lengthen the swingarm (3 cm) at the same time to fit a wrf wheel and its 245 mm disc.

Confident welder!!!
Did you chop a WR swingarm? The chain adjusters are not ttr style.
Nice work!

fork and a wheel 250 WRF 2008 and Ohlins shock purchased during a TTR 250 white that made the race paris dakar (check serial numbers in ohlins France at PFP).  tough off road / good for road and travel

After travelling alone for 5 weeks in Morocco and Mauritania with a TTR.

I have started a work I have been thinking about for long time. 

A friend has given me a frame in bad shape (much better because if I fail I will not have regrets).

 

I want to set up all the back parts from a WRF 2009. Is a long term project (6 months).

 

I will have to redo the exhaust pipe and an aluminum tank. Thinner to fit with the seat.

Well
My plan was to do it all in 6 months.
But I have had several issues: work/travelling and above all a robbery of my material at my workshop.
The insurace finally have paid part of it.
Back to the project.
For now, slowly slowly, I only have bought the pieces for the project.
Included a 2 shock absorbers Ohlins from Gas Gas nearly new that I have adapted to my TTR for the length, hydraulic and the spring.
For now I'm traying it on my TTR and so far perfect.

Impressive ambition. I think you might regret the seat though, especially if the bike is more stable allowing you to sit down more often.
I would love to see some pictures of you and the bike in Mauritania!

Thank you for the compliments.

there will be two ttr 250 the current one will stay like that. can be the ohlin gas shock absorber and the lithium battery instead of the toolbox in a fiberglass case.

2024 and 2023 I traveled alone. difficult to take photos with me on the bike

Verdict on the lengthened swingarm?

Verdict on the WR wheel, with larger rotor?

totalement satisfait de la modification. pas indispensable juste pour le plaisir de la modification. ma dernière modification (l'amortisseur à gaz est aussi une réussite) j'en suis totalement satisfait. j'ai placé la batterie (lithium) dans la caisse à outils d'origine (après deux essais fibre de verre non concluants). si vous avez des questions. je serai ravie de vous renseigner

totally satisfied with the modification. not essential just for the pleasure of the modification. my last modification (the gas gas shock absorber is also a success) I am totally satisfied with it. I placed the battery (lithium) in the original toolbox (after two inconclusive fiberglass tests). if you have any questions. I will be happy to inform

Please tell us more about the rear shock, what model gas gas was it from, how did it fit? did you have to make any modifications to it?

sorry for my english. lots of modifications. almost all gas gas shock absorbers (125/200/250/300 2 stroke) measure 43 cm, you have to extend to 45 cm with a spacer. extend the adjustment rod by the same value. redo the lower and upper rings. and especially modify the ttr connecting rod so that the adjustment wheel does not touch (i will send photos of the ohlins made for ttr and the gas gas) it is a financially unfeasible operation if you go through a professional.
