Hi guys I am looking for information for my ossa 125 tr i 2014

Can you tell me if I can find sprockets to replace the broken one (visible in the photo).

At first I thought the engine was broken and no it was a piece of the kickstarter broke inside the gearbox and this broke a tooth of the pinion I would be sad to have to throw the bike in the trash when everything else is working perfectly.

Can we replace them with another brand? Gasgas Sherco....

 THANKS

 

Wow, this is only the second TR125i I have heard about!  Do you mind telling us where you live (country)?  Please don't throw the bike in the trash!

The OSSA TRi gearbox is unique and gears from other manufacturers won't fit.  In fact, it's much more difficult to disassemble than a typical geqrbox.  Some information may be found here: https://www.ossa-efi.com/home/engine/gearbox

All the EFI OSSAs use the same gearbox.  Some spare parts were available, but it may be easier to find a complete gearbox.

Thank you for your response. 
This is not good news. 
I live in France. This explains my googol english 😁^^
if anyone has a gearbox I'll buy it

Try this company in The Netherlands: https://nonstopmotoren.com/?s=ossa&post_type=product  At one time they rebuilt OSSA gearboxes.  They will only deal with EU countries.

Thanks 👍  🤞🤞

Lewisport in the States had a jig to replace parts on those gearboxes and had quite a lot of spares.  I would check with them and see what they still have

👍 Thanks a lot.
