Available only in 1994 and 1995 in the US, the Mystic was a factory custom based on the BMW R100R. The changes were entirely cosmetic, but they were not insignificant. Nowadays a ‘special edition’ just means new paint – the Mystic had several restyled parts.
According to The BMW Boxer Twins Bible by Ian Falloon, changes for the Mystic included the red paint scheme, black frame, lower handlebars, restyled sidecovers/seat/tail section, shorter license plate bracket, a different angle for the muffler, and some chrome-plated pieces.
This example (VIN: WB1049702R0400053) has a healthy 60,534 miles on the odometer but fans of the drivetrain will line up to tell you that these boxers can do hundreds of thousands of miles without major issues. This bike has been slightly modified with dual-sport tires and a Fox rear shock so that you can “commute, [or] travel long distance/off-road on weekends”. Per the seller, only 276 Mystics were imported into the US and he/she has over $7,800 in receipts. The only flaw is claimed to be a small but unfortunate dent in the tank.
