as one who has as my biggest bike a 300 (279 actual cc's?)..I am enjoying this newfound focus on small displacement bikes. Honda sure seems to be leading the pack with this..Grom, Monkey, Super Cub, Trail 125, etc...The Grom was even copied by Kawasaki and Kymco with their versions of little bikes.
Not sure about trails (except Trail 125?) but for a second bike to mess around on, why not? Even better if they help to get some new riders interested.
