in all fairness wr300 and 310for stoke you could not give an honest report i liked the 300 wr it had good power but wont start in gear the 310 did not seem to steer as well the track was 1and2 gear stuff if you could ride them for half a day on tracks that you know and move the controls to suit you would know if you liked them but first impression of the wr300 it had good power
