If youre hardcore enough you can daily drive a rebuilt 70cc e50 puch maxi if you take backroads without highway speeds, this includes sealed wheel bearings, all new rubbers and cables, reliable lighting and a parts base larger than most other moped brands. These bikes simply need more maintenance than a car especially when pushed harder. It is doable though and I haven't driven my subaru in 2 weeks because the weather has been so nice.
(PS i still hold my respectable opinion of the boss pipe. with a high grabbing clutch and the right spring/ fluid combination it accelerates really nicely. yes ive tried estorils i have one on my tomos, but the boss hits hard in the real high rpms where local cruising speed is.
