If I want to get 75 mph or so out of the 250, will the stock 500 weights fit in the 250 to allow a bit more speed out of the transmission without redlining the engine? Or are the CVT components different enough to allow such a switch?

No they will not. If you go 1 gram less in weight, your RPM's will go up, but you may be red linning it at 75. If you go 1 gram more in weight it will drop your RPM's, but the 250 may not have enough power to get to or maintain 75. I would leave it stock and ride it the best you can. If you want to really tour, sell the 250 and get a 500. There are some super deals out there right now. :-*

250 rollers are 23x18, 500 rollers are 28x22, but the 23x18 are very common and range from 15 gram to 26 gram so just try a slightly heavier than stock weight, even though stock top end sholud be 85 MPH.
A slightly heavier weight may help, so weigh your current setup and see where to go from there.

The transmission doesn't red line on speedometer til 80 mph, but when the engine reaches its 7500 rpm red line you are only going 65 mph. Many others comment the same performance. If there was an easy way to get 5 to 10 more mph I would like to try it, but I do hate to modify from stock when it comes to the engine and transmission since I figured they knew what they were doing when they designed it. I may just wait for the xciting 400 or get a 500. I do like my 250 very much, I just wish it would go 70. This limitation keeps me off any stretch of interstate, and a new Interstate is opening here in South Western Indiana this fall.
