70cc Yamaha Aerox in London, Essex for sale

I am selling my Aerox as it has stopped running and I cant be bothered to fix it as I'm getting a car soon. I recently had a brand new Stage 6 MKII 70cc kit fitted along with a brand new Stage 6 exhaust. When running it goes about 80mph flat out and pulls off real quick. Its also got a malossi air filter, malossi belt, Stage 6 rollers and a quick action throttle. Electric start has never worked but always starts on kick (when running) all lights and speedo are working. I dont know what exactly is wrong with it something to do with the kickstart/variator probably. Its MOT'd till october this year and I have the full logbook. All in all spent about 1300 on this bike but as its not running ill take 650 and am open to reasonable offers. Complete bargain give me a ring if interested 1 buyer will need to arrange pick up. Only accepting cash payment at pick up.
