For people who need replacements for the hard-to-get parts on TY250s, there are replica flywheel covers, replica inner rear guards, replica oil pump covers etc etc.
Not only are these things available off the shelf, but look they came off a MOTO GP bike ie made of carbon-fibre composite material. It would be a shame to paint them they look so cool.
I have no idea what else they have except that they have electronic ignitions for Cota 348s, which I was having a squizzy in the first place.
