The Bike that Azz and I looked at today in Carterton is a Yamaha SR125; mine does not look like the one to the Right.

The SR125 is sold as a learner or commuter bike, the page for the Yamaha SR125 on the manufacturers site states:

Easy to manoeuvre, simple to use and featuring an electric starter and enclosed drive chain, the Yamaha SR125 is an ideal machine for new riders and commuters. Driven by a highly reliable 125 cc 4-stroke engine that produces a smooth band of power, this economical motorcycle is one of the most rider friendly bikes in the class. Natural riding position, slightly raised handlebars and pillion grab rail make for high levels of comfort for you and your passenger, while the low seat height and compact dimensions ensure lightweight handling around town.

And in other places listed as:

Totally reliable learner legal motorbike, seems to be the prefered choise of the majority of Motorcycle schools as it is virtually indestructable.A light easy to ride 5 speed electric start bike that will rarely let you down.

Hopefully it will put up with my riding style, i.e. 100 odd miles in a single trip, with no stops. It is being Delivered to Azz’s tomorrow about 14:00 so I will get some Photos then, and be fixing the broken throttle cable.
