What would it take to turn a 1125R into a Uly?
Tail section, front fly screen, headlights, etc....

Might be easier to mount the 1125 and its gear in the Uly chassis.

I think it's inevitable IMHO. That the powerplant replaces the Thunderstorm across the board.

I don't think 146HP in a Uly would be an advantage but Triumph's triple in the Tiger is a detuned version of the Speed Triple I believe. No reason a 120HP Helicon-powered Uly wouldn't rock.

Actually it might be easier to turn an 1125R into a "Uly" than vice-versa. Final drives are on the wrong side.

I haven't ridden one yet but from what I read, the 1125 would be perfect in a Uly. An added bonus would the weight savings.
I'm in.

Dont get your hopes up. The air cooled power plant is used because Erik likes it. Read the newest issue of Fuell and read Erik's comments on the air cooled line.

I dont know about yall but I have a hard enough time keeping the front end down on a stock Uly with no luggage(I can pull 3 gear wheelies to the balance point easier on the Uly then my Bolt.).

It would be fun but I see me shelling out coin for a 120 hp Uly.

Oh yeah, I do think bolting the Uly parts to the 1125 would be much easier than trying to stuff a motor in a frame that was not made for it.

more likely it will end up in a "sport touring" set up. 146 hp on the dirt is obscene amounts of power, and alot of mud rooster tails : D

Cityxslicker, So you don't just possibly maybe think that the Rotax might could be tuned for more low-end torque and less peak horsepower? My money is on the Buell engineers to appropriately re-tune the engine were it to be used for a Uly-type application.

ALL bets off till we see it, but in its current configuration, that thing would be a dirty beast to handle. (I didnt say it wouldnt be fun)

I think they will keep the air-cooled lump. Much of the R&D has been paid for. There are several who like it and would hate to see it gone.

We know that the HP's and torque can be increased substantially. If they just bumped it up a bit, it would keep the line attractive for years to come.

Why would the 1098 or Hypermotard mean that the Monster line had to die? Both have a place. I think they would within Buell as well.

A lot of people are ready to scrap a great motor for a new motor that they haven't heard run yet. The new Rotax might be a great engine, and it might make more power, but will it feel as good as the bike I'm presently riding? What kind of fuel mileage does it get? What kind of maintenance is required, and how often?
I'm quite happy with the "antiquated" pushrod engine. It has extremely low maintenance, is durable and makes adequate power for my needs. It also delivers great fuel mileage. And it gives my Uly a "Personality" that no other bike can match.
There are a lot of bikes that make more power than my Uly, but not one of them feels as good or is as much fun to ride.
I'd hate to give up that silly grin it gives me.

I agree with Crusty, I'd use the MPG far more than the extra 45 or so HP. And the over sqare twin will not get the mileage our beloved air cooled lumps get.

But that Rotax does sound sweet in person : )


living close to the Buell factory does have it's advantages from time to time

I'm not entirely sure I *need* a 146hp "adventure" bike. The current motor seems quite appropriate. I can see the Helicon being morphed with the Uly into some sort of a world class sport-tourer. . . I've got a clear mental picture of that.

My favorite car is still my 71 super beetle. I love the old air-cooled motors. Doesn't mean I wouldn't look at the rotax if available but I wouldn't give up my air-cooled for it unless it was a proven reliable low maintenance motor. I would just as soon spend dollars rebuilding my 07 Uly motor the way I would like it. Cam, jugs etc...

I can see an 800 or 900cc Helicon motor in the Uly of the future.... delivering 100+ HP, lighter weight, and still capable of world class fuel economy. Another advantage for a sport touring adventure bike would be that the Rotax mill can allow a larger fuel capacity in the frame.

I can imagine though that Buell will continue with the air cooled XB line for some time into the future as they are great motorcycles and the R&D is already done.

If the Rotax turns out to be as good as I hope it is, I say put it in the Uly. Just because it has 146hp doesn't mean you have to try and use all of that in the dirt. It just means a little more throttle control. On the blacktop that extra power would be appreciated.

I'd like to see that! Maybe attract more riders to Buell. At least now there's lots of different options to be looked at.

There is a business fundamental here. HD can make a few more or a few less v-twins for Buell and it will not affect their business very much.

But for Buell, I can assure you that the cost of the Rotax mill will change with volume as will the cost of the 1125 frame etc. It may not this year but in coming years there will be economies of scale that will be compelling.

Buell has a history of standardizing on fundamentally well designed parts. This is evident in the great interchangeability within the XB family. If the Rotax mill delivers on it's early apparent promise then it will be hard to prevent the spread of the successful design.

I would not expect Buell to makes this move abruptly but it won't take too long to see the writing on the wall.

Just my 2 cents musings....

Excellent thread.

The future's so bright, I gotta wear shades!
