Dry weight 2005 Rocket lll 705 lbs., Roadster ABS 809 is what I'm finding. Touring 870 lbs. The specs seem to vary according to model and source.
...and I've read from a couple of different now-forgotten but seemingly credible sources that the R3T is likely 30 - 40 #'s heavier than the listed "870 lbs".
My own '14 R3T (purchased new in '15) is now right at 8 thousand miles with the original Metz's. I've been meticulous with the suggested air pressures and am a conservative rider, not hard-torqueing on starts, no routine hard cornering, which an R3T isn't made for anyway), and though
I LOVE this Trumpet, I have to say the tire wear - particularly on the front - is abysmally poor. I've never owned any machine that didn't typically get 1.15 to 1.5 X the wear out of a front tire over that of the rear... yet here, that formula seems reversed. Factoring in my intentionally VERY light acceleration to save rear tire wear, my front Metz appears that it won't go but perhaps another 1k at best, and the rear maybe that plus a tiny bit more. Of course there are folks here that will say I've gotten "good" tire mileage at these figures, but I suspect it's because they ride harder than I do in acceleration and cornering. Most bikes I've owned, even the cruisers, might typically get 12 or 13 k on a front with my riding style. In my best cases recalled, I think I pulled something near 12k on one particular Dunlop rear on my '96 Honda ACE 1100 (still have the bike; bought new in '96...
great bike of the mid-weight cruiser class, but even these 1100 V twins produce enough low end torque to really "work" on rear treads if you're romping on 'em constantly, which I do not, typically), and almost 15 k on one particular Dunlop front. That bike uses classic spoked rims w/tubed tires, of course, bias ply. I've had other bikes produce similar tire wear results to these "bests", also. (Yes, I realize those machines are lighter than the R3T, but I still do not "buy" the excuses for the poor tire performance of these OE Metzlers on the R3T.)
To sum up, I've never seen a front tire wear out as quickly and oddly as has the R3T's Metzler, and the rear isn't doing much better. I say "oddly", as these Metz's may use a staged tread hardness design, where the cornering part of the tread is softer than the "straight line riding" middle part. There's a definite squared-edge center "stripe" of tread on the Metz front that's wearing - albeit still too quickly - a bit more slowly than the canted (cornering) part of the radius, and it's very obvious when looking at it. All this being said, I don't care anything about supporting Triumph dealerships in such lavish fashion (high dollar tires every year or more, potentially, and they also want nearly $200 for a flamin' oil change. I've NEVER had these kinds of routine maintenance costs with any other bikes I've owned. I did my own oil changes (usually) on my other machines, but the big Trumpet, here, is a bit more of a "different deal" on that, with the weight, low clearance, etc., so I had the dealership do my first scheduled change. Also, did I mention, "I DON'T LIKE THESE TIRES!" ? LOL......
(UPDATE: re-looking at the front tire, I'm not sure it's going to make another 1 thousand safely. All of my griping aside, however, let me repeat: I really do
love just about everything else, thus far, about my R3T, and bought it with the thought that it would be my "last" bike.... big, powerful, heavy, solid, durable, comfortable and should last for the rest of my "riding days", hopefully. Though not "old", I'm almost 63, and I can't see myself needing or wanting to handle anything any more stout than "The Kraken", here... lol....)
