    Curious to know how many trikes registered in the US and evolution of registrations over time. After the bagger, do baby boomers retire from biking or do they go into trikes? Harley is offering only one model, so a marginal market?

    Hi Brett, Just giving a response answer to your question from my point, not as of CH. However, I am a baby boomer, and I also ride a Softail and a Nightster (2 wheels). Didn’t retire yet from biking, but I bought a HD Street Glide Trike a couple of years ago just because it gave me more power. I am short 4’11” and handling a regular 2 wheeled SG was just too much for me. I saw the trike and walked away at first saying “Nahhh I’m not that old”. LOL, I defend that now because I do ride 2 wheels and this trike is awesome as far as touring for me. When I rode to Sturgis I discovered how many trikes were and are on the roads today. I see them more and more. I think sometimes only trikes see trikes because they are, well, a trike. There was a vendor renting out trikes in Sturgis and he was booked throughout the rally. One thing I will say though, believe it or not, it takes a bit more strength to ride one of these. You have to muscle the cornering, but once you get in sync you are good. There have been a few trike fatalities because of people thinking they are easier just because they have 3 wheels. I think this generation is still youthful in body and mind and having a trike for those who lose balance, and we will, is great. Just my opinion here from my own experience. Glad to see at least someone is curious.

    Just bought a trike and ridden a few miles. Made the move for health reasons after 15 great years on Big Dogs. It is different but wife is really digging it. Will be at Sturgis this year on a HD trike.

    Having owned a sevicar back in the 60’s and a side hack in the 70’s and2 wheelers the entire time I say that if I couldn’t ride two wheels I’d go to 4 wheelers. A 3 wheeler is fun for what it is, but it is not a substitute for a 2 wheeler.a 3 wheeler has all the disadvantages of a 2 wheeler and 4 wheeler in one vehicle with none of the advantages.

    Each to his own. I’ve been on Harley’s since ’68 and I have found that a three wheeler is a great substitute for a two wheeler in every way, except having the ability to lean into corners. However the trike allows me to do something that you could never do on two wheels, “drift” around corners! Bottom line… there are no disadvantages for riding any kind of vehicle. You ride what you enjoy. But I hope people don’t turn the trike thing into a Harley vs Honda, or Chevy vs Ford kind of bashing. We’re all in this together so let’s celebrate instead of criticize.

    Hey Joe, Didn’t Kenny Roberts invent drifting 2 wheelers?

    I few years ago when HD made a business deal with Lehman I speculated that Harley would launch a trike in few years because of the emerging market – bikers getting older, disabled, safety concerns, etc. – a lot of room and not much completion.

    Brett, as far as a marginal market goes I think you’re mistaken. Harley only offers 1 model but the number of conversion or custom builders is pretty big and getting bigger. Just google motorcycle trikes and you’d be amazed. The market will only get bigger. Cyril featured Paughco’s kit a while back right here as a matter of fact.

    Kathy, look into getting some raked trees. A little change in trail will make that Street Glide handle like a Sporty.

    I’m with you Joe. I’ve been riding (legally anyway) since ’66 and trikes exclusively since ’81. I absolutely love mine. Well, my 2 anyway – my wife loves hers more than I do.

    I service more than a few trikes and personally do not like the way ANY of them handle. Don’t get me started on Voyager kits……….. peace

    Hazy, thank you. I will inquire about that. I am no wrencher but I’m always looking to change up my bikes. Thanks again!

    I think that the trikes are scary to ride and handle in northeast with gaping potholes while in a turn! I will simply stop riding if this is my al;alternative …maybe take up boating at that point in my life when this occurs! did an independent trike kit that is fairly acceptable in corner’s !?
