Lot 495: Benelli Grand Prix Racing Motorcycle

Grand Palais Sale, Bonhams (7 February 2013)

Although it was first seen in 1960, the 250 Benelli four did not race competitively until April 1962, when Silvio Grassetti debuted the bike at Imola. Although eliminated by a bent valve in that first race, Grassetti stunned the racing world a week later at Cesenatico, beating the seemingly invincible works Hondas of Jim Redman and Tom Phillis. The great Tarquinio Provini was signed for 1964, but even with a seven-speed gearbox and more power, Benelli found it impossible to win a Grands Prix. Development continued into 1965, an eight-speed gearbox being new for that season, but by now Honda were fielding a six-cylinder 250 ridden by the best rider in the world  Mike Hailwood. Spreading its limited resources even more thinly, Benelli pressed ahead with developing a 16-valve 350 and a 500 (actually 413cc). With Provini forced into premature retirement through injury, Benelli signed Renzo Pasolini who promptly rewarded his new employers' faith by winning the 250 and 350 Italian Championships in 1968. In 1969 he reaffirmed the 350's competitiveness by beating MV-mounted reigning World Champion Giacomo Agostini six times out of seven in the Italian Championship. By this time the last of the Japanese manufacturers had pulled out of the World Championships, clearing the way for the Benelli fours to grab a slice of Grand Prix glory. Agostini and MV Agusta remained unassailable in the 350 and 500 classes at World level, but in the 250 category Benelli eventually got the better of Kent Andersson's Yamaha and Santiago Herrero's Ossa, Australian Kel Carruthers bringing the Championship back to Pesaro. There were sporadic appearances by the 350 and 500 fours over the next few years (four-cylinder 250s having been banned) but that glorious 1969 season effectively marked the end of Benelli's Grand Prix campaign. The Benelli four re-creation offered here consists of a Harris Performance Products frame, copied from an original loaned by famed Benelli collector Giancarlo Morbidelli, and a 16-valve, seven-speed Benelli engine built by Morbidelli Equippe. It is an accurate re-creation of the Pasolini-era Benelli 350s that challenged the mighty MV Agusta team during 1968/69, and incorporates the last developments employed on this model. The Benelli was acquired by Team Obsolete in 2006 and raced by Stu Carter at Mid-Ohio in 2010. Team Obsolete then treated it to a major rebuild with a new Falicon-improved crankshaft and Nikasil-plated cylinders. In July 2011, Dave Roper rode the Benelli to a win in the 350GP class at the Mid-Ohio Vintage Days meeting. It is now in race-ready condition with only 100 miles of track use since the rebuild. The vendor believes that it is the best of the six examples extant. Included in the sale are alternative rear sprockets, pistons and valves together with detailed rebuild notes, race records and technical information. Additional spares are available from the vendor.
