The Yamaha BT1100 Bulldog Platform
The BT1100 Bulldog was introduced as a distinctive road-focused Yamaha with a 1,063 cc air-cooled V-twin engine and upright riding position. PartsNMore listings currently identify BT1100 applications across specified 2002–2006 model years. Use that year range only as a starting point: the exact product listing, dimensions and confirmed reference number remain the final fitment checks.
Some BT1100 service items also list Yamaha XVS1100 or other models because individual components can be shared. That does not mean the complete carburetor, intake or engine assemblies interchange between those motorcycles.
