New axle nut fitted.

[BikerCraig]

Suzuki put a rather shoddy looking axle nut on the sv but I found a bloke on ebay selling stainless axle nuts for a few models of triumph (some of which fit the sv. . . rocket 3 and late gen daytona 675 ar a couple) and after putting the new nut on along with a set of bibio's stainless adjuster plates it looks lovely, and at 7 quid I'd say a bargain when compared to 15 for the same thing from pro-bolt. Check on ebay for anyone else interested in upgrading their nuts ;)

A link would be useful :-P

Are the nuts self locking?

I did a search on Ebay and unless I'd picked the wrong ones, they don't appear to be self locking nuts

[BikerCraig]

No they are not self locking, never seen a self locking axle nut on an sv to be honest. Standard nut wasn't self locking?

Yup, the standard nut is self locking.

If not self locking then bike manufacturers would usually use a drilled axle/cotter pin arrangement...Kawasaki tends to use that.

[BikerCraig]

Is it, the one that came off my k3 is just a smooth backed flanged 24mm nut and so was the one on my previos sv a k5?

[21QUEST]

Certainly is self locking on the Curvy and I'd doubt it'd be any different on the Pointy.

Every bike I've owned, from my recollection, has either come with a self locking nut or a cotter pin arrangement.

Personally, I wouldn't use an axle nut that wasn't installed using an arrangement that prevented it from backing off.

[r0ddy]

Really? I was under the impression they were not self locking as I'm pretty sure any bike I've owned has had a standard flanged.

As you seem pretty confident, Just out of interest what makes the nut self locking?

As far as I wa aware the only way to do that was with a nylon insert, castellated nuts or the two metal fins to lock the nut on.

[21QUEST]

Probably easier to put up some links.
First link shows the type usually used on bikes.

EDIT: I was typing as you edited your post.
Indeed, different methods can be used to prevent the nut backing off. It's possible a case of you just not noticing.

[BikerCraig]

Fair enough, ive had all the opposite, 03 sv, 05 sv, and 02 bandit 6 all with a normal flanged nut just torqued to spec. If I was truely that worried I would put a spot of locktight on it but ive never had a axle nut come loose. Pro-Bolt is the other option and theirs has a captive washer but that's 15 quid for a nut

[tigersaw]

Is there something special about stainless axle nuts, are they just metric thread?

I have about 30kg of assorted stainless in a box here

[21QUEST]

That's probably because they've all been 'flanged self locking nuts'...like the rear sprocket nuts :p ;)

[Sid Squid]

21Quest is right - all the standard spindle nuts are self locking. Some other countries do not allow this and thus a castellated nut and split pin is used.

None are 'just a nut', stainless or otherwise.

[daveyrach]

I got a replacement axle nut from Suzuki for my Curvy and it was the same as the old one which was not self locking.

[r0ddy]

Come to think of it, I have noticed that you can't ever spin an axle nut on by hand.

That's probably why!

[Sid Squid]

It's all making sense now!
