David Roper Of Team Obsolete To Compete With This AJS 7R3 “Triple Knocker” To this Year’s Manx Grand Prix 

AJS-7R3-Triple-KnockerThe Manx Grand Prix motorcycle races, scheduled August 23-30 this year, are held annually on the Isle of Man TT “Mountain Circuit” course for two weeks, and this year marks the 90th anniversary of the race.  The ‘MGP,’ or ‘Manx’ as it is more commonly known, is considered to be the amateur riders’ alternative to the original Isle of Man TT races held in May and June. No other motorcycle race is held on such a challenging track. This nearly 38-mile mountain course requires intense skill and courage, with its never-ending series of bends, bumps, jumps and stone walls.

The event consists of six four-lap races of the 37.72-mile (60.70 km) circuit that begins at the TT Grandstand in Douglas, the Island’s capital. The separate classes are the Newcomers Class, Lightweight/Ultra Lightweight Class, Junior Class, Senior Class and the Junior/Lightweight and Senior Classic races for older machines. 
Roper’s AJS 7R3, one of only four ever built, will compete using Avon’s AM20 90/90-19 on the front, and AM18 100/90-19 on the rear. More information at the Manx Grand Prix  and at the Isle of Man competition,

    Dave Roper IS the man of vintage racing in the US. The only Americian to have won a senior event at the island, back in ’87 on a Matchless G50. Drum brakes and 2″ tires doing 106 average lap times!
    He’s got a great blog – http://daveroperracing.blogspot.com/
    Good luck and hope the triple knocker stays together.

    Riders in the Isle of Man TT are the very best riders in the world , not the bunch of lames doing wheelies on our freeways here in SoCal, who think they are red hot riders.
