    If the belt case was easier to get into, I would experiment with some Dr. Pulley sliders. I think the acceleration could be improved on real slow-speed corners. Seeing how I don't ride the Dragon very often, I'll leave well enough alone. The Tmax has a pretty strong mid-range.

    One thing I dislike about the Tmax 500 vs my Burgman 400 is the heavy engine braking at low speed, that on off feel. I have to be more gentle with the throttle.

    I read that is result from having a high compression engine.

    No way to correct this I assume?

    It's not so much to compression, as tranny. Pre -13 Burgmans have even more of this, but riders used to it don't even want to change.

    How is it the tranny, geared differently?

    I have the 2009 model

    In Burgman 650 it is the CVT controller map -- it slows down in low gear ratio, contrary to new models in which controller keeps ratios higher. The TMAX cvt must be geared lower comparing to the B400.

    Does the Burgman have some type of electronic control on the variator? I thought it was strictly done by weights and springs.
    I would think it would be more to do with a twin cylinder vs. single cylinder engine.

    The B650 does. Both B400 and TMAX are weight -- torque-multipler-spring CVT which can be farther tuned.
    Usually the pot capacity contributes to engine braking.

    I knew the 650 did. I thought the discussion was concerning the B400 vs. Tmax.

    Yes, I was comparing my 09 Tmax to my 06 burgman 400.

    My tmax has 11 to 1 compression ratio.
    Not sure what my b400 is.

    I assume the bigger the cc, the heavier the compression.

    Had them both too, while TMAX had harder breaking than the Burgman indeed, it was still nothing comparing to the B650. Compression ratio for K6 400 AFAIK was 10.2 to 1. But don't think the difference influenced breaking much.

    so still why the dramatic difference in engine braking?

    I got the scooter mainly to ride the mountain roads around here,
    when I get to more desolate areas, I enjoy real slow speed riding to enjoy the scenery.

    I want to test the nc700x to see if it's like this also...


    BTW, when I accelerate hard off the line, I hear like a "groaning" sound, not loud but can be heard.
    I heard this sound before on my Burgman 400, others said it was common noise from the clutch bell.
    But the tmax uses wet clutch, so should be no sound??

    I really like the strong engine braking on the TMax. If I want less of it, I back out of the throttle less. With full engine braking, "brakes" are not even needed in normal riding. In spirited riding, I have never noticed the bike "coasting". It always seems hooked up to power. If I want to power out of a corner more, I have to set the entry speed so that I can. Again, with the strong engine braking that is easy to do. It only comes comes loose from the clutch at very low speeds as I am stopping. As far as the engine braking on the NC700, there is very little - even with the manual transmission, but especially with the DCT. In addition to weak engine braking, it has fairly puny front brakes and a joke of a back brake. Having owned both, I don't think I would have any trouble in the twisties showing an NC700 the disappearing taillight of the TMax.

    RE: the growl. I think it is the CVT belt on both. I have no Burgman experience, but my understanding is that the Burgs use a centrifugal clutch.

    Regarding the battery and bodywork, The bodywork is extensive, but only overwhelming the first time or two. Battery access is not bad at all, though you have to carefully release the four snap connectors on the top of the front center cover (after removing the two pushpins under the nose). Then remove the windshield cover with a few phillips screws.

    Since T and Lardy have 360 deg crank, the resulting breaking effect is as if it was from a bigger bore pot. Moreover i have some reasons to believe the T's gearing ratios are a bit lower than those for the B400.

    What do u mean by pot?

    360 deg crank? Meaning both pistons go up down together?

    Lardy is the b650 or b400?

    I am also thinking the heavy engine braking is from having 2 cylinder vs 1 cylinder

    yes, the B400 uses a centrifugal clutch with a bell, like most scooters.
    not sure how the tmax one works, all i know is that its a wet clutch.

    and yes I see the advantage of heavy braking in riding the twistys, but my one pet peeve is the low speed riding part. (@15-20mph)

    I gonna meet up with someone local on FB, he has a CTX700 (which he complains about low speed dct issues)
    we will trade bikes and see.

    I guess I will answer my own question, LOL!

    pot is slang for cylinder.

    Lardy is slang for a Burgman 650

    360 crank
    https://en.wikipedia.org/wiki/Straight-twin_engine


    Also, I did read on the Burgmanusa forum people adjusting the idle speed to get the engine braking effect they desired....

    Rode a CTX700 today, just around a parking lot. semi-interesting....
