Tomos electronic E90 tuned / / JJ exhaust

Tomos electronic e90 - Slovenia
From begining slight uphill. at the end quite uphill. So it has different performance in straight line. Gears are quite long to achive nice travel speed - rpm compromise. Top speed not yet tested but for now 100km/h wiht no real struggle. Whole RPM range is usable, but it works best from 6000 to 8500RPM.
