|Featuring a semi-automatic gearbox and handlebar-mounted brake levers – just like on a bicycle – the Yamaha TT-R90 has been specially designed for smaller children. As well as being a whole lot of fun to ride, this 4-stroke minibike helps kids to develop important machine handling skills at a young age – skills which will undoubtedly be of use in the future.|
