What Visordown found
Visordown says the engine changes produce 93 bhp and 51 lb-ft of torque, with 80 percent of that torque available from above 3,000 rpm, compared with 80 bhp and 47 lb-ft for the Trident 660.
It says that on the mountain roads above the tester's town the softer suspension started to cause some issues when pushed, and that the basic engine block and casings are the same as the Trident 660 and Tiger Sport 660 but the rest of the bike has more in common with the Trident.
The same source adds that the geometry is new, with a steeper rake, less trail and more of the rider's weight over the front end.
Geometry and hardware in numbers
The brakes are twin 310 mm floating discs with four-piston radial calipers and a 220 mm rear disc, all with ABS. The tank holds 3.7 gal and the bike weighs 443 lb wet, 26 lb more than the Trident.
