    Thanks for the replies so far.  I think I'm becoming more accustomed to it.  And £1K for an front upgrade:

    Nitron: https://www.trident660.com/index.php/topic,207.msg935.html#msg935

    ... seems ridiculous money at this early stage in the game for me as a Noob.

    I have 1800 miles on mine, Iím 5í11íí and 185 and find the suspension is very cushy, yet extremely stable over bumps at high speeds.  I have my rear preload at 7 for one person riding but honestly I donít notice much of a difference between 1 and 7 from a stiffness perspective. it does change how the bike behaves and for me it handles the choppy bumps far better with the spring preload all the way up. When it was set at 1 I was getting bucked around awkwardly.

    Iím surprised to read the bike is harsh and unstable for some people, that just doesnít sound characteristic of what I read and have experienced. Makes me wonder your front and rear wheels are out of alignment.

    I also agree the psi is too high, should be 32f 36r. Theres some information in the manual that looks suspect. Not sure if anyone else is seeing the same thingÖ.My printed manual says the tires should be 32front 36 rear in the maintenance section. The downloadable manual specifies nothing in the maintenance section and in the specifications section it says 42r 34f! Big difference. Bolt torque specs canít be correct either.  My physical manual that came with the bike says the chain adjustment nut should be torqued to 9 lb-ft, the online version says ď27 lbf  inĒ. Huh?! I google it just to make sure and sure enough 9lb-ft =108 lb-in. That means my manual is telling me to crank that with 4x more torque than it probably should be. Moral of the story is donít completely rely on the manual, always check for reasonableness when wrenching on the bike. 

    Someone help me out, Whatis ďlbf- inĒ!? Is that the British way of abbreviating lb-in or did someone screw up the manual?

    Just sayinÖ

    I could be wrong, Iíve been wrong once before.

    What page in the manual does it say the tyre pressureÖi cannot seem to find it  :138:

    Also it sub tropics does it need to be lower than our cooler climate brethren as 42 seems quite high?

    Just curious what others have it sat at, especially those down under (for 85KG persons).
    Cheers

    Understand these are meant to be 'cold' pressures. I would have hoped the Owners manual would be specific for the country the bike is sold in so may be different.

    I personally run the above temps during the summer and will drop them a couple of psi's in the winter - just my personal preference of course.

    Do not listen to the manual for tire pressure. The stock tires work better at 33 front and 30 rear. I've been riding it that way and the bouncing isn't as bad. 42 is way too high for the rear.

    Do you mean 33 front and 40 rear? 30 rear seems really low unless its for the woolies.
    Im personally 32 front and 40 rear right now

    Iím running 32F and 36R with good results. Still under break-in and not pushing hard into corners. Iíve found all Michelin tires to have a harsh ride due to stiffer sidewalls. On my previous bike I replaced the OEMís with Dunlop RS IV with fantastic results. Iíll be doing the same with the Trident when the time comes.

    I just checked my tire pressure and ive actually been running 32F/36R, I remember reading some posts and dropping down a while ago and the bike has handled much better, no bouncing in corners or going over highway bumps.

    I've heard pretty good reviews of the Dunlop RS IV and they are supposed to get longer tread life than the MR5s but I like how the Road 5s keep their wet weather performance after wear.
    They are both premium options though at $200+ a tire

    I'm running 30f 38r for the mo. Roads are cold with ambient around 8 to 10*c. About 85kg in my riding kit. I think it takes a bit of the sting out. Hoping that in warmer weather, warmer tyres and damping oil it will soften up a bit. Plus only done 450 mls so things might loosen up a bit. I don't reckon the ride is much better than my 43yr old 350Guzzi.
    Does anyone know how easy it would be to change to thinner oil in the forks?
    Bikes from a 53 bantam to a 95 Trident 900. And now a 660.
