I did not know about the 2020 Gas Gas using sealed bearings. I do know that other brands have been doing this for years with great success.

Beta Alp 200 would be a good choice.

I have had several of the Beta 4t trials motorcycles and have found the stock gearing to be the best.

Apparently you need the complete rear brake system from a 1997 Gas Gas

I think you may have missed 2020

Find an AJP or Beta (grimeca) front caliper this will bolt on with very few issues. On the rear , I believe that there is a retrofit assembly available, I do not remember where I have seen it on the internet. Good luck.

Maybe try the " blue label " fork seals I know several people that have had good success with this brand.

Most likely a remote reservoir for the rear shock. It even has a ZF ( Sachs) sticker on it.

Good info !

The engine is not the same. There are minor differences.

There are no superfluous fasteners on a modern day trials motorcycle ( all brands ) Modern day trials motorcycles need all of their nuts and bolts to be tight, so that everything works properly. The ONLY way to be sure that the nuts and bolts are tight is to check them. Particular attention should be given to brake disc bolts and rear sprocket bolts.

The keyway on the Techno crank is in a different spot. the con rod kit part number you are looking for is 11.03720.800 I think this is what you are looking for

the rear shock is rebuildable

my understanding is that air cooled bikes 120 PSI is about the max cranking pressure

you should try to get in contact with members of the local trials group " ATAQ "
