955 chain adjust 2 and a half inches?

[Sport]

During my ride Sunday while at a gas station a guy rode in on a 955 with his chain hanging way down, at least 2-3" of slack.  When I pointed it out to him he said Triumph recommends about 2 & 1/2" of slack.  That can't be right can it?

I believe most specs are ~1.0-1.5" of vertical slack travel.

3" is one loose assed chain.

That's what I figured but he was a grown man so I didn't argue with him.  His bike was filthy and loaded only with a backpack bungeed on behind him.  Even my daughter noticed it and from watching me adjust my chains, mentioned it looked kinda loose.  I didn't really believe the Triumph would really make such a recommendation.

As I recall from my days of Sprint ownership, the slack should be 30 - 40mm (about 1.25"). I used the "lift it with my toe" method. If I could easily touch the bottom of the swingarm with the top of the chain it was too loose. I always went for the loose end of the spectrum.

35 to 42 mm on my 2003 speed triple,about 1.50 of an inch at tightest spot

If its anything like the 1050 Sprint then its 35-40mm or 1.37in to 1.57in

Exactly the same according to my handbook.

Same here.  All three Trumpets were the same; 00 and 04 RS and 02 Trophy.  

I will say that 1.5 inches of slack looks like a lot.  But it always worked and I got excellent chain/sprocket life.

The way the geometry works on the Triumph is that the chain gets tighter as the wheel travels upward thus the need to have it, seemingly, excessively loose when the bike is unloaded.  Also, if the rear wheel adjuster is in the proper, stock, position and becomes loose enough to slip the chain will get even looser.  You can lower the rear of the machine by turning the rear wheel adjuster (it is an eccentric) 180 degrees; if the adjuster comes loose in this configuration the chain will go full tight...not good.
