Back in the 60s and 70s a wave of small bikes from Japan (mostly) led to a surge of popularity for motorcycling in the USA. Then in the 80s the popularity of small bikes fell off as riders moved to bigger and bigger bikes. Back around 2006 When I was selling bikes there were very few small street bikes available here. It was not uncommon for the dealer I worked at to not have a single under 500cc bike in the showroom. Recently the number of models of small street bikes available in the USA has steadily increased. It's a great time if you are a fan of small bikes. The Grom started the tiny bike surge and has been joined by the Z125 and Kymco Spade. Every manufacturer offers at least one small "sporty bike" 400cc or smaller. There are super moto's, cruisers, and a bunch of 300cc and under scooters available. My question is this. Are the manufacturers responding to an increased demand for these small bikes or are they hoping to create a demand by offering some more exciting bikes in the small displacement/low cost segment? Will millenials be willing to buy these small bikes. Will older riders be willing to downsize and buy these bikes? Will displacement "creep" mean that over the next decade these small bikes will keep getting bigger and become midsize bikes? Will we repeat the cycle of the past? Personally I'm a small bike fan and I see most of my future bikes being around 300cc or under. I for one hope that small bikes are the wave of the future and not just a fad. This only applies to the USA as small bikes have always been popular in most of the rest of the world. So what are your thoughts on this subject?
