The 250 Jonway I just disposed of showed 4000 RPM at 50 mph. This Honda Reflex I just got shows 5000 at 40.
The Jonway speedometer was fairly accurate--3 mph high at all speeds.
Any 250 riders with comparisons to share?

It all depends on how you have your CVT setup, heavier weights will bring down your rpms lighter weights will raise your rpms at the same speeds.

OK, so where is the treatise on weights?

What is the weight of the rollers in a standard Chinese 250 variator? This Honda turns many more rpms for the same speed and I do a lot of long distance cruising. Does the entire variator for a 250B/YY250t fit a Reflex

It also depends on the speed.
My BMS TXB 260 EFI stock had 1000RPM's for every 10MPH,
eg:
50MPH = 5000RPM
80MPH = 8000RPM
but under 35MPH the numbers where not correct anymore.
2000 RPM from 0-5MPH
3000RPM from 5-20MPH
3500 RPM from 20-30MPH
4000RPM from 35-40MPH

When I was looking for parts for the scooter I got from you I saw a list of weights for the cn250 that went up to 26 grams. The small one was 16 I think. I figured I would try the 20 if I replaced them.
I would think the variator would be interchangable but do not know for sure.
Earl one of the mods here has owned a coouple of them and I bet he would know. JR has the linhai motors in his I think.

Doug, I particularly liked the one on the Jonway. For a brisk take off it would go to 4000 RPM and hold that until about 50 MPH and then climb from there.
Since I normally cruise 50-60 it seldom ever went over 5000. Exception: when I had to get on freeways and needed to keep up.
This Honda goes to near 6000 then drops back some but only back to 5000 at 40. Haven't had a chance at open road yet to see what it does at higher speeds.
May be up in your "neck of the woods" in a week or two.
