bobber chopper with 1125 rotax motor

[kjmarko83]

Ok, so I'm getting ideas together to build my first custom bike. I have inverted front end from ultma and am going to buy a softail frame from demon cycles (cheaper). i haven't worked out all the measurements yet cause im just not sure on the motor part, but i know its going to be a hell of a frame mod to put the 1125 motor in there. the reason im using the softail frame is for a more ride-able bike over all. i don't want to build a show peace. im going to ride the piss out of it and have the best (as can be) of both worlds.

I've looked around the interweb with limited time and haven't found much as far as putting that motor in a softail frame but i assume it will be like any other buell motor in a bobber.

does anyone have any thoughts on this before i put my money in a 1125 motor. if its a bad idea then im just gonna build a beefy evo motor and be done with it.

Why the 1125 Rotax? Just wondering, I know nothing about the motor. If you want to make power you can probably do what you want a lot more economically with a evo-pattern engine. If the Rotax is a means to scratch a itch and you have the knowledge and resources to do it, then hell yeah, and post some pics!

A rotax in anything would be sick, I'd check and double check part sources though. If you can get it done proper like, I'd say go for it.

I had a 1125r back in 2008 and loved it. 140 hp and that thing would hall balls. why? I figured its a solid motor, seeing as how i ran the piss out of it like a 16yr old on his first bike and never had a single prob from the motor. its built strong and would have no need to go into it and add performance parts. plus you can find them in bike grave yards some what easily, or ebay. my old one is probably still sitting in the bone yard in Austin, TX. they wanted 2,000 for the hole bike a year ago and I figured i'd put the same amount of money in to building an equal power motor. So why not 1125, I say to myself.

the only reason I didn't buy it already is I'm gonna look for something a little less ravaged my mother nature. 4yrs in a junk yard is gotta do some damage.

Oh and I guess its just a cool factor too, having the only one on the block!

Go for it. Post some pics.

Oh, and i'll definitely be posting pics of it through out the build. i just have to get started on it first. probably going to start in January due to funds.
