stages before the company went into voluntary liquidation towards the end of that year. Vincent Motors Vincent Motors USA founder and president, Bernard Li, acquired the Vincent trademark in 1994 and formally launched Vincent Motors USA in 1998, spending about $2 million building prototypes that resemble the original Vincent but utilised modern components like the Honda RC51 V-twin engine. Vincent Motors was based in San Diego. A resurrection of the Vincent name is now unlikely as the RC51 engine is out of production, and Li was killed in a single-bike crash in Arizona in 2008. Irving Vincent The Irving Vincent is produced in small numbers by HRD Engineering (Horner Race Development – Ken and Barry Horner) in Hallam, Victoria, Australia. Announced in 2003, it is a re-engineered version based on the original Phil Irving drawings, with engine capacities of 1000 cc, 1300 cc or 1600 cc. Apart from the basic elements of the design, the Irving-Vincent was fully updated, with modern metallurgy, casting and milling allowing far stronger engine construction. The first Irving-Vincent was 1299cc in capacity, had a 14:1 compression ration, ran on ethanol and developed around 135 hp. Subsequent models increased the engine capacity to 1,571cc, developing 165 hp, followed by a four-valve, fuel injected engine of 1,600cc developing 180 hp and a top speed of nearly 170 mph. The marque gained worldwide recognition by winning the Daytona (Florida, US) 'Battle of the Twins' in its first attempt in 2008, ridden by Craig McMartin. Plans were made to return to Daytona for the 'Battle of the Twins' with the 1,600cc engined model, but this didn't happen.
