March 26, 20197 yr I ran across an old OSSA here in the USA and I need help identifying exactly what it is...I just can't figure it out. The owner says it's been sitting in storage for 30 years and was told the bike is all original. The handle bars mount to the top fork yoke with U-bolts. The Frame number is B251002 and the engine number is M250154. I'm leaning towards it being a 1967 Pioneer based on the engine number and the large front hub, the rest of the bike looks like a Pluma/Plonker. Any help is appreciated. I'll try to post pictures...I don't have any right now.
March 26, 20197 yr According to the numbers it's a Pioneer (US name for the Ossa Enduro). Plonker has a 24mm IRZ, Pioneer is a 29mm double needle.
March 26, 20197 yr That looks much like my 1970 Pioneer 4-speed did. The ‘scrambler’ tank was used on some, others used the larger fuel tank.
