Sorry about the four fifty confusion. I guess I can see how you would interpret "four fifties" as 450cc bikes rather than four 50cc bikes...

I thought the rs50 was a street motor. The RX50 is the motocross version. Are the motors the same?
I don't know if they're the same. I just happened to find a bunch of rs50 dyno charts so I went with that. I assume they'd at least be similar. The numbers I used were from a stock 50cc cylinder with an aftermarket pipe. It makes about 8 hp. When I told you they made 12 hp I was wrong. The 12 hp bike had an oversized cylinder.
I'll have to see if the RX50 has lower gear ratios. For the RS50 I took 2 teeth off the front and added 2 to the rear for the stock setting and it's still too high.

Is anyone started on bike models for these?...Looks kinda retarded riding around on a full sized bike..hahah
Love it though...Just thoughts of 85cc 2 strokes in the game ..always wanted them...Also makes reminds me that this game has no limits \
Great job jiv ...
For the small bikes, someone would have to make a model for the bike, tires, and maybe a rider too in that small mini position. It would be cool to have a little kid model too.
I don't read European( ), but found this image on that site... no way this is a 50cc bike. Either way they are still fun, and I'm all about putting together a series for these, lol.
