    What alternative to the bike toolkit C spanner do you guys use?
    I'm thinking there must be a better quality, more usable item out there for workshop use

    I have heard others say they use a blunt long flat screwdriver and a rubber mallet...

    In my owners hand book they say the slack should be 21-30mm, but i noticed in the workshop manual some of the the speed triples are 30-40mm,not sure why that would be?

    my work shop manual covers from 2011 up until the new model came out it just seems weird that they are quoting 30mm-40mm for some and 21mm-30mm for others in the manual, i didn't think there was any difference between a 2011 and mine which is a 2014

    Thanks for the tip Jack, just bought one - looks the part with long handle.
    I had to adjust my chain half way through a Spanish tour in the grounds of a remote farmhouse gravel yard whilst the local rooster pecked my legs as I lay covered in dust on the floor - that shit toolkit spanner did nothing to improve the situation!!

    Look for underboat96 on eBay. That's who I bought mine off when I had the sprint GT.
    Keeping mine just in case I ever get another one :)

    Yeah, that's the one I posted a link to before.

    The spanner is high-quality and the long handle gives better leverage.

    Amount of chain slack required is dictated by geometry/relative position of drive sprocket - swing arm pivot - suspension travel. So differs from bike to bike.

    Didn't look at the link. I agree the spanner is good quality. Handle is a good size not too long that if you were on a long trip that you can't take it with you.
    Certainly does the job better than the one you get with the tool kit.

    Thanks for the recommendation Jack - I've just ordered one from Underboat96 and it was dispatched immediately. I can't vouch for the item yet, but the seller is very efficient.

    He'll just need to knock up a few more to meet the sudden demand :)

    Yeah, I was thinking about that. I should have asked him for commission!

    You'll be very happy with the tool - it's much, much better than the spanner in the toolkit.

    I suspect I'll miss the way the handle falls apart just as I get the toolkit version into position ;)

    Re chain tension Triumph need more than most due to the relative positions of output shaft to swing arm pivot to rear spindle.
    Best is to start with about 25 -30mm of slack get someone to sit on the bike(heavier the better) and then see if you still have some slack. Push down on the rear as much as possible also.
    A chain that is tight will do an awful lot of damage.
    At the TT one year noticed a bike that the chain was like a bow string (Kawasaki ZX7R). 1st lap over Ballaugh bridge the engine was pulled in 1/2 at the output shaft.
    That's the worst case but can certainly wear out chains etc very quickly
    Btw my streetona (96) needs a good 40mm

    i think with the 2011 and maybe later speed triples (it just goes with engine numbers so not sure of years) the workshop manual say 30mm-40mm but for mine which is a 2014 (same model as the 2011) they quote 21mm-30mm:confused:
