UK designer John Wrightson has designed this brilliant security device for your bicycle or motorcycle:
In-Lock is a locking point for any Mountain Bike or Motorbike while at an outdoor event or camping. In-Lock's main aim is to deter any opportunist thief.
In-Lock works by having the pin screw into soft ground and it then cannot be pulled out. The hole in the main body of In-Lock allows a lock or chain of any shape or design to be used to secure a Mountain Bike or Motorbike of any make or model.
In lock is essentially a NI-CR-MO pin which runs right through an impact modified Polypropylene main body. The NI-CR-MO pin is the same material used on locks and chains currently used within many security products currently on the market. The polypropylene body alerts people that the Mountain bike or Motorbike is secured by the use of bright colour and provides extra protection to the pin.
Although this is just a design thesis, the idea is great, especially for use with lighter motorcycles like the R5 or RD, or dirtbikes. Sometimes there's just nothing to secure the bike, or you don't have a chain long enough to go around that pole or tree. This little device is ingenious and I hope to see it make it to production.
This is a site dedicated to the 1970-72 Yamaha 350 R5 two-strokes. These bikes are surprisingly fast for their size and age, lifting the front wheel in the first two gears and keeping up with modern bikes twice their size. It's also extremely flickable and great fun around the city or carving up canyon roads. It was the direct descendant of the Yamaha factory TR production racers. Dirty, loud, crazy quick and relatively affordable when new (and more so now!), it was, and still is, a giant-killer.
I picked up an R5C for my first motorcycle a few years ago, and was frustrated with the lack of information on these bikes available on the web. The original purpose of this site was to document the process of bringing the R5 back to life. But as I spent time gathering as much relevant and entertaining information as possible into one place for my own reference, I thought it would be helpful to share it with people who are also interested in these bikes, as well as other Yamahas, vintage bikes, and cool motorcycles in general.
