I have a 1999 Lem Condor. It has a moto morini S5 motor from a KTM dirt bike that is rated for 6hp. Stock hp is 2.5. It has Renthral bars, twist grip, foot brake. It has a modified expansion chamber with a forest legal FMF turbin core spark arrestor. It is widened with custom aluminum wheel spacers.
The Condor is very small. There was no room underneith it to run the new pipe. I swung the pipe out the side going around the floor board. There is plenty of room for kids feet and it has worked out very well.
I have owned this quad since it was new. I have two boys that learned to ride on it. This quad is more than just a lawn quad. It has plenty of power for real trails. $350 Durand MI
