Hub-center steering has been around for a while (the concept of it was documented in as early as 1920's) but Vyrus combine that with Omega frame, Fomula 1 car like rear shock and a carbon-fibre monocoque tank and seat unit. Currently, Vyrus and Bimota are only production bikes that feature hub-center steering. Yamaha made GTS1000 in 90's but did not do well.
