I installed one one on my S2 Fazer last year (2016). GIpro X type gear indicator by Healtech. Also has a shift light facility. Bit fiddlt to fit when working in the area around the abs unit, but if your bike doesnt have abs, then it should be straight plug and play. Im dead chuffed with it, worked as soon as installed and set, plug and play. Only slight downside is that if you ever disconnect he battery, the shift light defaults to 6k, and has to be reset back to your preference (mines 12k). I paid £99 and im well pleased with it.
