I already had a ground anchor 19mm 1.5m chain and a Squire SS65CS to secure my old Sportster.
I changed bikes and bought a Street Glide and decided to add the APP rather than just buy a longer chain.
After my attempts to measure the pin I needed, I opted for a 490mm (thanks for the help and advice), it's a perfect fit behind the rear cylinder on top of the transmission.
Its a very heavy duty piece of kit, well made, and was delivered less than 24hrs after I placed my order.
Thanks for some great service.

have a honda xr 125l pin fits through bottom front end of frame just perfect.could have got away with the 340 mm pin but as long as chains are tight under frame its no bother.to sum up pin,padlock & chain just perfect cheers.

Superb product Does what its designed for fits through frame and chain to provide secure loop from anchor.440mm fits Harley FLSTC.What a pleasure to find good quality products and helpful people will be doing business with you again kind reguards Daz.

I couldn't be more pleased if it came wrapped up in £50 notes. Makes locking by bike securely quick and clean, unlike the dirty, slow, knuckle skinning effort it was before when trying to wiggle various chains and locks through holes in the bike.

After searching for a chain sturdy enough yet small enough to fit through the small link in my ground anchor, I came across the anti-pinch pin on the BMW GS forum. It solved my problem perfectly whilst offering solid protection in a convienient way (it is so easy to fit that I know I will use it every night). The service was friendly and delivery was very fast. Thanks Steve. A+++

Bought a Pinch Pin, Ground Anchor, Chain and Padlock. These are very well made and tough products. The service from Pragmasis was excellent with regular updates by e-mail on the progress of the order (thanks Steve).

I highly recommend these products to anyone who is serious about Motorbike security.
