Those are sh*te, you can break into them with a toffee hammer... for a PX you want an Oxford XD5, they don't sound off with an alarm but they are good at slowing up thieving f**king scum... They have a 5mm pin to go through the brake disc but watch for some of the scumbag sellers on eBay, they all should come with a reminder cable, they shouldn't be sold separately.
Had a cheap one on my r6 Even with a reminder cable ,,,I forgot Pulled away and broke the lock,,was glad it was a cheap one as I would have dropped the bike (off balance) Might have broke the disc!broke the brake caliper More of a deterrent than anything ANYWAY,,,,I DONT HAVE A DISC 🤪😀😀
On the tubeless rims there is a cutout so you can get one of those wire plastic coated cably type things through it to bolt to a ground anchor.... Bet you have standard rims too scooterg... You git... ✌️🖕😆
