This one is the "Racer" model, suitable for most sports bikes (see internal dimensions above). It's Thatcham approved (recognised as a ground anchor). It's basically a fortress.Now, they're simply not available in the UK at all. I'm moving house and will have a garage, so don't need it anymore, otherwise I'd keep this thing forever.
Never lost a moment's sleep with my bike locked up inside of it. It's a bit weathered now, but still solid with a few paint chips around the edges.
