The "sell" imperial quages. Now. does this mean that your local dealer will have them in stock... Ur, maybe. But Defi makes the gauges in PSI. I did notice that the size for the PSI option is smaller. They don't carry many larger than 52mm. But that was the size I wanted anyhow. I plan on puting the Boost on my stearing column.
