Overview[edit | edit source]

Ducati 750 TT1
















The TT2 and later TT1. These spectacular machines were similar to Tony Rutter's four-time World TT2 Championship-winning TT2 racers. Modeled closely after the factory TT2, the production version also featured a 597cc engine using special two-ring Borgo pistons (weighing only 408 grams). Valve sizes were 41mm and 35mm, and racing camshafts provided 11mm of intake valve lift and 10.5mm of exhaust valve lift. The crankshaft and con-rods were highly polished, with a new steel clutch and straight-cut primary gears. The clutch was a cable-operated wet type similar to the street bike. All TT2s were fitted with an oil cooler—the 1982 version had a cylinder head bypass, while the 1983 TT2 received a full-flow cooling system with stainless-steel lines. 1983 TT2s also had a steering damper. All TT2s came with an electric start. Ignition was the usual Bosch BTZ, with the battery situated in the tailpiece.


The compact Verlicchi frame with cantilever rear suspension was shared with the factory bikes, as was the racing Marzocchi fork with magnesium fork legs and adjustable rebound damping. The Marzocchi rear shock had a remote reservoir and adjustment for both compression and rebound damping. Wheels were magnesium Campagnolo, 2.15 x 18-inch and 2.50 x 18- inch in 1982, with a wider 3.50 x 16-inch front and 3.50 x 18-inch rear for 1983. Brakes were 05 Brembo Gold Series with fully floating disc rotors. For 1984, a factory 750 kit was available to transform the TT2 into a 750 before a limited run of TT1 replicas was constructed. These were basically the earlier TT2 fitted with a 748cc engine. The Valve sizes were identical. These catalog racers were heavily based on the Tony Rutter 1984 TT1. The Verlicchi frame was the same except for a wider aluminum cantilever swingarm to accommodate the wider wheels. The Marzocchi fork and Brembo brakes were shared with the TT2, but an outboard countershaft sprocket allowed for the larger-section 18-inch rear tire, with an endurance-style quick-change assembly. This allowed the disc and caliper to stay in the swingarm as the wheel and sprocket were removed. The front wheel was still a 16-inch.


While largely unappreciated, except by the cognoscenti, the diminutive TT2 and TT1 were among the finest of all catalog Ducatis. In many ways they epitomized Taglioni's philosophy of maximum performance through light weight and simplicity. There was nothing superfluous on the TT, with function determining the form of every component. Source Ducati author Ian Falloon
