rieju century 125 unbridled checks before chasing top speed

rieju century 125 unbridled forum question

Someone asked about rieju century 125 unbridled and seems to expect one hidden switch. I think the real answer is model year, legal limit, service condition and measured road tests.

I found this related page while comparing notes: rieju century 125 unbridled. I wanted a practical thread before guessing.

Would you check exact model, legal rules, GPS speed, chain drag, sprocket ratio, clutch slip, valve clearance, plug color, intake leaks, exhaust leaks and fuel range first?
