This is our RCJS negative 1 inch steer plate for the Yamaha SJ. Quick steer, increase steer ratio, improve handling, and our short plate allows you to move further forward in the tray for increased nose pressure. Works with aftermarket hande poles wit our bearing kit, see below. Will also work on a stock SJ pole, but you will need to drill 4 holes forthe bearing plate. Please email with questions. Thank you.
