Montesa172 Posted September 20, 2023 Report Share Posted September 20, 2023 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 Quote Link to comment Share on other sites More sharing options...
konrad Posted September 20, 2023 Report Share Posted September 20, 2023 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. Quote Link to comment Share on other sites More sharing options...

konrad Posted September 20, 2023 Report Share Posted September 20, 2023 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. Quote Link to comment Share on other sites More sharing options...

lotus54 Posted September 28, 2023 Report Share Posted September 28, 2023 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 Quote Link to comment Share on other sites More sharing options...
