    1100 vs. 1200 frame?

    I've got just about a whole Rex in parts. 2 1100 frames & a 1200 frame, 1100 engine. Problem is only the 1200 has a title. I know the 1100 is a little steeper rake & trail than the 1200, but is that in the triple clamp? Any idea how close the frames are? I'm thinking I wouldn't notice much difference running at 1200 frame w/ 1100 triples. Thoughts?

    Re: 1100 vs. 1200 frame?

    Swingarm pivots are 5mm apart, 1200 swingarm is longer, and the 1200 triples offer increased offset. This is what accounts for front end geomety differences. I believe the steering head is the same angle for 1100 and 1200.

    Oh!! One last thing.......................................I think you'll be fine running 1100 triples on your 1200 frame. I'd do it on my track bike if I had a spare set of 1100 triples.

    What does that mean?

    Currently putting a 1200 swingarm on a 1100 frame (yet another ZRX project) - that shouldn't be a problem, right?

    And visa-versa, an 1100 swing arm should mount up to that 1200 frame?

    thanks for the info man!!!

    Yes, the swingarms are interchangeable.



    The pivot location on the 1200 frame is 5mm higher I believe.

    Re: 1100 vs. 1200 frame?

    I've owned both, but I don't have specifics like them guys do.

    I just know the 1100 handled a hell of a lot better than the 1200 does; especially on the "goat trails" we have around here. (I also had better suspension components on the 1100 I sold like a dummy.) The 11 was "easier" to "toss-into" corners, seemed to "steer-quicker" & was slightly more unstable than the 1200. I rode the 1100 on the track a few times & it was fine, I would not attempt it w/the 1200 until I get it better suspended (it sucks bad right now.)

    So, I'm not really comparing apples to apples, more like apples to oranges. My 1100 had frame braces, steering damper, widened up rear wheel, Ohlins, Racetek Forks, JEMM under frame brace, etc. The 1200 is bone stock & it really shows in the corners. Someday hopefully I will be able to fix it up...(sigh)...

    Stock to stock, I've found the 1100 to be noticeably more flickable than the 1200.

    Stock?? Who leaves 'em stock?? I don't know that "flickable" and ZRX can be used in the same context.

    Re: 1100 vs. 1200 frame?

    I'm dragging up an old thread, rather than starting a new one, to find out any differences in the frames between the 1100 and 1200.

    I have a 1200 with Ohlins forks and shocks, a braced swingarm and 156hp motor that I wrote off recently, so I have bought an 1100 to swap everything over to.

    I've only stripped the 1100 so far, but so far I have found the 1100 frame swingarm pivot is 5mm higher, the 1100 triples have 2mm more offset (giving it less trail), the rear tank support is different on them (so the underside of the tanks are different too), the 1200 has one extra plate welded to the top of the steering head, and the 1100 has a mounting bracket for the lower water pipe on the down tube of the frame.

    Apart from these changes, does anyone know any other differences between the two frames? Also, does anyone know if the extra bracing on the 1200 is worth doing to the 1100 frame while I have it stripped?

    Good question. I donít know but seems many or at least some things are identical. I would be interested to find- out about the frames as well

    There is a shoulder at the rear tank mount on the 1200.

    Yeah, that was the tank support I was referring to. I'm thinking of cutting it off the 1200 frame and welding it to the 1100 frame so I can use the bigger 1200 tank on it. I might take some pics of both of them tomorrow to show everyone else what we're referring to.

    The 1200 tank is 1 litre smaller than the 1100. The 1200 was braced to try to improve handling. The aleady braced 1200 swinger should bolt up to the 1100 frame

    Re: 1100 vs. 1200 frame?

    I believe the mounting point for the rear shock is relocated on the 1200.

    Maybe KWICK can confirm that with a side-by-side comparison of the the arms.

    That's why I want to run the 1200 tank (it doesn't get the best fuel economy with the engine mods and I'm about to put flat slides on it too), plus I have two 1200 tanks and only one 1100 tank.

    The extra bracing is what I am hoping to find out about. I have seen the extra plate welded to the top of the steering head, but I'm hoping someone knows what else is braced and where.

    The plan is to put the braced arm in with the Ohlins shocks and Galespeed wheels.

    The upper mounts look the same between the two frames. I think the difference in the mounting points is in the swingarm. I know the 1100 swingarm is also shorter than the 1200 swingarm.

    You don't need the rear tank support . I've been running 1200 tanks on my 1100 frame for years.

    Here's some pictures of the difference in the steering heads and the rear tank mounts.

    you can just cut the shoulder off the 12 and bolt it on the 11. no need to weld, unless you want to.

    Re: 1100 vs. 1200 frame?

    So the last point of difference in the frames I noticed was the lower rear engine mount. The 1200 has a beefed up mount on the frame and a steel bracket bolted to it and the engine mount and the 1100 has a simple tab welded to the cross-brace that the engine mounts straight to. I would assume the 1100 mount was a week point for them to beef it up so much for the 1200.

    Re: 1100 vs. 1200 frame?

    So the mods I've decided to go with on the 1100 frame are:

    Add the gusset to the steering head as per the 1200 frame

    Replicate the 1200 lower rear engine mount

    Add the rear tank mount from the 1200 frame

    Add a 25mm cross brace between the upper shock mounts (just behind the plastic tub)

    Gusset under the bend in the spine of the frame with larger pipe bent to the same angle welded on the underside of the bend


    I have also purchased the K-Factory down tube that ties the two down tubes together at the engine mounts.

    It will be at the fabricators for a couple of weeks, then it's off to the powdercoaters. I can get some pictures of the changes and put them up when I pick the frame up if people are interested.
