Hey folks. New here so don't be offended by my ignorance. I own a 2009 Thunder Mountain Keystone. I love this bike. For me - it has it all: looks, speed, big fat tire, lots of chrome, and best of all, the heart and soul of HD. I know many of you may not feel that this is a real HD, but I mean to tell you - the way this baby is built - it screams HD quality and reliability all the way down the road.

My reason for being here is that I do not see a lot of chatter about these bikes. I know the company went out of business. Yeah, they didn't know too much about economics, but they did build some gorgeous machines before they left. All with mostly HD parts! Mine has the Screamin' Eagle 110, Baker six speed, all HD controls wiring, lights, brakes, and instruments, all posted to a super stretch gloriously painted custom frame that is so well balanced, it nearly stands up by itself. I know I have heard some bad stuff about these bikes, but then how many people are actually posting threads to the forum when everything is working great?

I’d like to get some honest intel on these machines, the company, and who is riding these. Perhaps get some chatter going so we can help one another with questions, information, etc. I know I have lots of questions about my bike and would like to share them with some other folks who own the Thunder Mountain products.

So – is anyone out there riding a Thunder Mountain? I’d like to talk with you. Good or bad news. Send a note, post a thread. I’ll be in touch.

Thanks for reading and ride safe.

how many miles is that? I'm too lazy to map it and you should know anyway!

A buddy of mine has a 2006 TM, not sure of the model, Keystone maybe? He lives just outside of Denver and bought it new from TM in Fort Collins. I was with him when he bought it.

First, for the negative: As far as any owners manual or shop manual there's no such thing. When he bought it, they told him that they could provide him with a "build sheet" which would list all the parts used to build the bike, but they "had to find it" and they would mail it to him or he could stop by later to pick it up. My buddy called or stopped by around once a month for the next year and a half and always got a song and dance regarding the mythical build sheet, so he finally gave up. My guess is that after 18 years you won't be able to get anything from TM Harley, but who knows? It's probably worth a call to find out.

Second for the positive: Although it's no longer his primary ride, my buddy still has the bike after 17 years. I think he's put around 75,000 miles on it, all trouble free. It's been as reliable as my 2007 Harley. Like hellonewman said, it's got a HD factory drive train, with the exception of the exhaust. Just as important, it's got a Harley wiring harness, electronic components, and handlebar switches. The electrics were a major failing point for lots of the clone bikes.

Also like hellonewman said, the core of the bike is a Harley Softail. I've studied my friend's bike pretty closely, and it's almost all HD, with the primary exception of the frame, and then various other small things. I hope you enjoy your new bike. My friend's bike is the red and black one in the picture below:
