Triumph Tiger 1050 2010 Front Fork Seal Replacement.

Hi Guys,

I'm new to the forum but I'd just like to post a message about my experience with changing the front fork seals on my 1050 Tiger.
I did a lot of searching for info but it seems very slim on the ground so had to wing it a little.

Firstly the fork removal is very straight forward with just the usual two lower fork tree bolts and one upper bolt plus obviously front brake caliper and front wheel removal. Make sure you loosen the top cap first cuz you'll never loosen it after the forks are out without much damage.

Once out and the top cap nut is loose it's simply a case of unscrewing the top cap and pulling the outer top section down to reveal the spring space.

At this point you'll need a special tool to compress the spring, this tool can be bought off ebay for £16.90 (Laser suspension tool 6353)

To compress the spring use the tool and a ratchet strap, once you compress the spring you can then see the nut just under the top fork cap and this needs to be loosened and then the top cap can be screwed off. All very simple and very similar to most upside down forks.

Where it gets confusing is the amount of oil to put in the forks before the rebuild. Triumph give two figures 580ml per leg and also 30mm air gap. These are both on the official Triumph data sheets.

What I did was to empty each fork leg of oil completely into different containers so as to gauge which triumph figure was correct because the internet says one or both are wrong.

So I can confirm both fork legs contain 580ml of oil however the air gap was much more than 30mm's (sorry I didn't measure what it actually was) but looking at the gap i'm guessing it'd be more like 100mm at least.

I totally believe if you set the oil level at 30mm you'll blow the seals in no time at all !!!

Basically just make sure you put 580mls of 10 weight fork oil back in each fork leg and you'll be OK. The seal kit I bought again off ebay was excellent quality and contained dust seals, fork oil seals and both sets of internal fork bushes.

If anyone has any questions I'll try and help however I'm no expert
