Sounds like a good start to determining the condition of the chain and sprockets.
I would suspect the 125 and 250 have the same gearing and parts for more economical and manufacturing ease. The 250 has about 18/19 HP so the 125 would make 10 HP at most. I would be sticking with the stock gear ratios as I think Suzuki has a good idea about that.
12.57 in = 31.93 cm.
Sunstar make most if not all OEM sprockets for Japanese bikes. If you do need new parts don't worry about the Sunstar quality if the package says Sunstar instead of Suzuki.
Front sprockets should always be made of steel although some rear sprockets can be aluminum because they do not wear as fast as the front. Stick with steel, it is cheaper.
Chain choice is O-ring or X-Ring. O-Ring is OEM and will work well. X-Ring is a bit superior but don't bother unless you can get it for the same price or a small difference .
Now we can wait till after the MOT and then start all over again with good/bad news to work with. :lol: :lol:
