This legendary dirt bike features ultra responsive front and rear suspension systems for agile handling and fast cornering – and is now fitted with a free race kit consisting of a Launch master system, GYTR by HGS muffler, GYTR by HGS exhaust, V-Force 3 reed block and a blue 48T GYTR alloy sprocket.
All that’s missing from the package is… you.
