Comparable bikes to our 600xr's

20 posts in this topic

Just as the title says, I want to see what other makes and models are comparable/competitve to our XR600R's and ofcourse their going to be older bikes but who cares lets go back a few years... OR maybe theres some new bikes out today that could still be considered competition, I just want to see what you guys have to say about that... Let the posting begin...

I'd say this means air-cooled. That gives the Yamaha TT600 and the Suzuki SP600. These are comparable to the 80's XR600. In the 90's there wasn't really anything. If you want to add in the street legal models, there are the XT600 and DR650.

I'm with cleonard, the SP and TT/XTs of the 80s where about the last similiar designs (save for oddities like ATK605s and the like).

I had a 1985 XT600. It had a weird dual-carb setup, one carb was slide and the other was CV. That thing was a bottomless pit of torque. It's been 10 years since I've had it but I'd bet it pulled harder from the bottom than my XR.

I also had a 1984 XR350 at the time (maybe I was a sucker for dual carbs?). Riding the 350 after the XT was like riding a XR100. It was totally gutless by comparison.

"O"

belive it or not i know it hard for some people but some time ago when white brothers was doing some R&D testing they gave my father som parts to test out for him they made him the deal if he put the parts on it he could keep them and they would do maintance and dyno the bike for free after all the parts and work they did the bike came out with 83 hp at the wheel

thats in excess of what cr500's make... a built cr500 would make 80-90hp, anything above that requires alcohol or nitro. I don't buy it

The highest HP figgures I have ever seen was from a HRC in house built Dakar bike which was in the neiborhood of 72 at the rear wheel. So 83 is probably very conservatively rated and on a dyno that somebody "calibrated" to win a bet!

That sounds like a challenge... cool, i like a good challenge.

If you could get it done and prove it, maybe even take a fellow TT member with you for a witness, then then scan the results into your computer and post it up.

I am very interested in the outcome of this.

The big question is.... will you gho through with this challenge.

OOOPS! Yes, yes I did! The bike is way trick, alloy tank, and all factory, since it was uh, a factory Baja or Dakar bike. Go to my website and the pic is right there on the home page.

I'm in the process of re-building a old 1992 XR600R desertbike and in pictures you can check out the slow progress I'm making if you want.

The ATK 605 is the closest bike I can think of to the XR600. They are still great bikes for dualsport.

I would be interested in the dyno sheet from that bike to compare numbers. I will get my motor dyno'd when broken in after my rebuild of my XL600R from 589cc into 618cc Thumper.I am hoping for at least 50WHP.I have all my parts for this rebuild except, I am waiting on a cam for this build to go on so result will be posted probably sometime around the end of Dec. or mid Jan.

Comparable to an XR600R? A mid 90's KTM 620 R/XC. Kick only, but watercooled. Had both, still have the KTM, but both are great bikes.
