Street Fighter® JK or you can search under gauges/gages/speedo/speedometer. I have not seen too many VFR street fighters around here thou. But you can see a few post on this forum as well http://vfrworld.com/forums/general-vfr-discussions/18219-need-aftermarket-guages-my-94-a.html
Options I found were: Trail Tech (the Vapor) Vapor: Motorcycle/ATV Tachometer Speedometer at Trail Tech Home available from Trail Tech directly or some supermoto shops Acewell 3853/3953 ACEWELL Digi Dash Speedometers > Motorcycle - Road / Custom / Race Replica available in Canada at any bike shop that carries the Motovan catalog but may be backordered for a long time. Koso Gauges koso north america, gauge, gauges, motorcycle gauge, car gauge, motocross gauges, automobile gauge, atv gauge, speedometer, tachometer As well as using a bicycle speedometer (the Filzer one at $10 from MEC works well) and a separate tach. I'm sure there are others, I used the Trail Tech and I spoke with another VFR rider that used a Koso and the caveat with both of these (as well as most electronic gauges as I understand) is that the tach doesn't know what to make of the VFR's uneven firing pulses and the tach will never read quite right - it jumps around a lot. If you do find one that works well, post up and let us know about it.
