hi, anyone had any bother with the front forks making a knocking noise under light load, makes a thud over bumps & when its on centre stand it knocks if u bounce front end lightly, phoned the local triumph dealers up & said they've had a few in with same problem, they have fitted new bushes In them & its not cured it,or are they just fobbing me off, basically they all do it & you'll have to put-up with it.
@Mark Thackray: At my wifes Tiger 900 with 20.000 km there are no "extra" noises. At the Tiger 900 of my father in law it is the same.
I hear a knock as the bike falls into small steps only noticeable at low speeds. Very evident as I start riding in the morning, perhaps it is temperature related. Later in the day I do not hear it I have not been able to reproduce the noise while on the side or center stand
Hi Mark, Yes I have a knocking noise. The bike shop (not a Triumph dealer) that I bought it from says its the floating discs, another independent mechanic said it was the headstock bearings and a Triumph dealer didn't know. My diagnosis (which may not count for much as I'm a total newbie to bikes) leads me to believe these is play in the top of the forks on the inside. I was able to replicate the knocking on another used Triumph 900 GT and a brand new one (both at the dealer). I discussed the issue with. To replicate put the bike on the centre stand, make sure the front wheel is forwards and touching the ground. Grab the wheel at the front and push/pull the wheel in quick succession. You don’t have to apply big force but some and obviously be careful not to pull to hard as the bike is on the centre stand. When I do this I hear a knocking noise at the top and inside the forks. When I did this at the dealer and it happened on 2 he assumed this is the way it is. This might be the case but I'm not convinced. I appreciate that the forks must compress/rebound and to do this there is some clearance but play suggestions too much clearance. NOTE 1: if the front wheel is of the ground and the bike is on the centre stand (as it you were checking for wheel bearing play) I don't get the knocking noise. NOTE 2: Both the bike shop I bought the bike from and the Triumph dealer agreed that it isn't headstock related. NOTE 3: when riding at slow speeds the knocking can be felt. The knocking is consistent but inconsistent. Consisting in that you can be guaranteed you will feel it a slow speeds and inconsistent in that it's not necessarily dependent on the road surface I.e.smooth or bumpy. NOTE 4: As I mentioned I'm a total newbie to bikes
