Honda VTR1000 Firestorm 1997-2005
 

The Honda VTR1000F (frame designation "SC36") was a 90° V-twin sport bike produced by Honda from 1997 to 2005.
Known worldwide as the Firestorm

The VTR1000F was introduced in 1997 using an all new 90-degree V-twin engine and a HMAS (Honda Multi-Action System) fork and shock.
The bike also ushered in several new design concepts for Honda such as the semi-pivotless frame, where the engine is a stressed member with the swingarm bolted directly to it.
Other innovations were side radiators, single-casting engine case, connecting rods with cap screws instead of nuts, and 38 mm intake valves, the largest Honda has ever used on a production motor at that time.
It had the largest carburetors ever put on a production motorcycle (48 mm).
In order to overcome response irregularities typical for larger V-twin engines, Honda figured out different camshaft profiles and intake manifold dimensions for the two cylinders, and the power control of the engine was praised in motorbike surveys

A new LCD dash display comprised fuel level, engine temperature, dual trip mileometers, odometer and clock.
A Honda Ignition Security System (HISS) immobiliser also became standard.
