A motorcycle with V-type engine employs a turbocharger and necessary components arranged in an advantageous layout such that it does not interfere with the rider's legs or feet. The turbocharger system includes a turbocharger positioned fore of the front cylinder, aft of the front wheel, and below the front exhaust port. The rear cylinder exhaust pipe routes on a horizontal plane adjacent to the lower area of the cylinders, as to not interfere with the rider's legs or feet. The turbocharger lubrication system includes a vented oil holding tank fastened to the turbocharger's oil outlet port, in conjunction with an electric pump to transfer the oil from the holding tank back to the engine crankcase for the reason that the level of the turbocharger oil outlet is lower than the level of the engine's oil sump level. The intake plenum is secured to the throttle body assembly by fasteners entering through the bottom of said throttle body that screw into tapped holes of the lower section of the intake plenum, such that the structure does not interfere or impede the incoming airflow.

1. A motorcycle having a frame assembly; a front wheel suspended from a fore section of the frame, a rear wheel suspended from the aft section of the frame, an internal combustion engine with cylinders in a V-type arrangement with a front cylinder and a rear cylinder including a crankshaft with the centerline axis in the lateral direction of said motorcycle, in which the engine is generally positioned between the wheels, said engine having at least one induction port and at least one exhaust port, a turbocharger system comprising: a turbocharger positioned fore of the front cylinder, aft of the front wheel, and below the front cylinder exhaust port; said turbocharger having a compressor with ambient air inlet and compressed air outlet, said turbocharger also having a turbine stage with intake and exhaust ports; an induction system which couples said compressed air outlet to said at least one engine induction port; an exhaust pipe configuration which couples said at least one engine exhaust port to said turbocharger turbine intake port; wherein said exhaust pipes are routed such that the rear exhaust pipe exits the rear cylinder exhaust port, then bends laterally and towards the front of the motorcycle and follows a horizontal plane along either the lateral left side of said V-type engine cylinders or the lateral right side of said V-type engine cylinders; then merges into a two-into-one collector before entering the turbocharger. 2. The motorcycle of claim 1, wherein the two-into-one collector is positioned longitudinally forward of the engine, with the front cylinder exhaust pipe above the turbocharger, and below the front cylinder exhaust port; the front exhaust pipe exits the front cylinder exhaust port facing the fore direction; then immediately bends downward towards aforementioned turbocharger, where it merges into the two-into-one collector with the rear exhaust pipe just above the turbocharger. 3. The motorcycle of claim 1, wherein an oil holding tank is fastened to the turbocharger oil drain outlet; said tank has an inlet port at the top of the tank, an outlet port at the bottom of the tank, and a vent port at the top of the tank. 4. The motorcycle of claim 1, wherein an oil holding tank is fastened to the turbocharger oil drain outlet; said tank has an inlet port at the top of the tank, an outlet port at the bottom of the tank, and a vent port at the side of the tank. 5. The motorcycle of claim 1, wherein an oil holding tank is fastened to the turbocharger oil drain outlet; said tank has an inlet port at the top of the tank, an outlet port at the side of the tank, and a vent port at the top of the tank. 6. The motorcycle of claim 1, wherein an oil holding tank is fastened to the turbocharger oil drain outlet; said tank has an inlet port at the top of the tank, an outlet port at the bottom of the tank. 7. The motorcycle of claim 1, wherein an oil holding tank is remotely mounted below the turbocharger, on the chassis, employing a hose to transfer oil from the turbocharger to the oil holding tank. 8. The motorcycle of claim 1, wherein an oil holding tank is fastened to the turbocharger oil drain outlet, an electric pump is used to transfer the lubrication oil from the oil holding tank outlet, to the engine oil sump. 9. The motorcycle of claim 1, wherein an air induction system employs a plenum which occupies the space between the engine and fuel tank. 10. The motorcycle of claim 1, wherein an air induction system employs a plenum which occupies the space between the engine and fuel tank, such that the plenum inlet faces the fore direction above the front cylinder. 11. The motorcycle of claim 1, wherein an air induction system employs a plenum which occupies the space between the engine and fuel tank, such that the plenum inlet faces the fore direction above the front cylinder; said plenum is fastened to the throttle body assembly such that the fasteners enter through the bottom of the throttle body assembly, through throttle body thru-holes, and then thread into the bottom of the intake plenum, clamping the intake plenum securely to the throttle body assembly.
