The difference to your bottom line is likely to be only about $100.
For that you get a larger, 19-inch front wheel (as opposed to two 18-inch wheels on the C5 Classic), a somewhat different riding position and a straight front fork as opposed to the offset fork on the C5 Classic. The fork is the same length as before, but with different geometry.
The C5 Special will be available in all 50 states.
According to a notice that went out to U.S. Royal Enfield dealers last week, the C5 Special will appeal to larger riders who find the C5 Classic smallish but prefer its styling to the B5 and G5, which use the 19-inch front wheel.
The new C5 Special will be available in all C5 colors except the Red Chrome.
