Has anyone else noticed corrosion on their rear subframe? My bike is a December 2015, so only 14 months old. Its the second winter i've ridden it through and i clean it weekly as well as i can, but there are spots of corrosion appearing on the rear subframe, The paint looks really thin. The swing arm is starting to bubble at the gasket too. The rear brake lever and centre stand are corroded to hell too!
