    I've had the bike now about 2,000 miles and have yet to get into that super comfy groove where the bike feels like an extension of your mind and body, as I did with the street triple.

    Meaning I'm way more conservative on twisties than I'd like.

    Changed tires, tweaked rebound and comp, but bottomline I still feel like I'm perched high on a bull and with a 5% forward pitch to boot.

    I hadn't messed with the rear suspension preload because the manual states fairly explicitly not to, but looking the manual for the Ohlins shocks themselves, there's nothing there to suggest you shouldnt.

    I took some measurements and my crude ride height number was 5-10 mm above the Ohlins reference at 42cm and the free sag was just above 20 or about 5-10 above reference.

    I'm tempted to drop that a few spins to take about 7-10 mm off the preload and perhaps that will have me less perched and lower the ride a tad.

    Thoughts ... anyone do this?

    FYI - Im ~190 and have the compression and rebound between road and comfort

    Sad that after 2k, Im juts not loving this and I think it just the ride height + forward cant and high rearsets making it seem more precarious than Im accustomed too.

    Thanks

    If you are 190 its time to give up riding ....(190 years old...) ;)
    Anyway, of course Triumph advise against it so you can;t blame them when you lose control after adjusting to make the bike unstable.
    If you measure sag properly I believe rear static sag comes out about 20mm as standard - measuring from axle to a fixed point on the upper body with bike raised of the floor then sat vertically on its wheels.
    I adjusted mine to about 14mm as I wanted quick steering (and it was recoomended by K-tech in Performance Bikes) it was only about a turn or two of the adjusting collar . If you wind the collar out a couple of turns amd measure, you should be close. It will slow your steering a little , You could also drop the front forks through the yokes a little to similar effect .
    Have you considered adjusting or changing the 'bars so you sit more upright ?

    thanks for the reply

    I didnt want to straight up raise the handlebars. I've done that to a few bikes (BMW R12000RS) but this didn't feel like that situation. It really felt like there was just too much preload on the rear booting the tail up.


    I (actually local shop) wound up taking a tad off the preload on the back, but then adding a turn to the front fork (which affectively raised it a touch to balance)

    seems to have half solved the problem. Steering seems uncompromised.

    Not track settings, but good commuter and canyons settings

    We finally got a bit of warm weather so i took it up and down the canyon and have tweaked the rebound / compression setting between the road and comfort settings - maybe a few clicks out from comfort on the rear - I dont have my notes in front of me.

    Still not as flick-able as my old street, but seems a bit more of a hybrid on between the two now and I may be ok with that.

    I dont know that I have much more room to adjust with my fat arse, but it was a step in the right direction.

    will be interesting to ride this side by side with the new street RS in the spring (and maybe a SDR) ... but I think its good enough to stall that.

    beats lowering the suspension which I really, really did not want to do.
