The main difference between the 2 models is the wheels. So using the bike for 70/30 on-road/off-road means choosing between the two models.
I like the slightly lower seat on the M, being a road bike rider from way back, and new to dirt. But to start into the trails and backroads I need something like a CRF (or KLX, which offers the same wheel dilemma with the D-tracker).
My question is:
Are the 17" size wheels on the Honda M a handicap off-road? Or put another way, are the 21/18 L wheels an essential component for off-road? And if the latter, are the larger wheels then a handicap on road?
