Hi there,

I've recently done a massive service in my 04 Gasgas Txt125. On replacing the rear sprocket, it's going to need some new bolts.

The bolts I have bought were too big, as were the locking nuts.

I've cut the bolts down, and filed down the nuts. They work perfectly, and tighten up properly.

My question is: Will these these bolts be okay? Or do you need to buy the specific sprocket bolts e.g. Apico bolts?

The once I've used tighten perfectly as I said, but I'm just wondering whether the Apico bolts are hardened or anything?

I just don't want to risk bending the bolts or ruining the hub!

Any help is greatly received.

Thanks abd regards, Jack.

It's not so important where you buy the screws and nuts!

Important is the strength of the fasteners, be sure to get the screws and nuts with the right strength.

I would suggest at least in DIN 267-3 / DIN EN ISO 898-1: 10.9 or SAE J-429: Grade 7

or buy them as original spare parts from your bike dealer.

EDIT:

And "Loctite" them too!
