rotax max is on a 2001 solo frame not the best make frame but straight and in good nick, had rebuild about 20 hours ago got ALFANO PRO data logger on stearing wheel
tkm i think is 115cc but never had the head off to see is on a solo frame not as clean as the other but still straight
then there is an unknown frame with a kx 80cc air cooled 5 speed this would be a good project for some one to put a bigger engine on something like a 250cc as it has all the linkages for gearing
also got an all round break kit with bias reservoir
