Royal Enfield V-Twin - The Musket

What you see here is a 700cc Royal Enfield V-Twin constructed using two 350cc top ends. The whole bike appears to have come from the factory, or maybe the “special vehicle operations” section, instead of the mind and work of a creative and determined owner. Aniket Vardhan, the builder, still wants to come up with a better exhaust arrangement, than short open pipes, but already, the bike looks fantastic. Aniket calls the 700cc Enfield V twin, “The Musket”, to keep the vintage gun (ala Bullet) reference alive.

Aniket's rationale and idealism....

1. Keep it as ridiculously simple as the original Bullet engine. Therefore, no modern updates to major engine internals
, so it still has the stock tappets, no hydraulics, and the stock piston oil pumps
. Vintage bike lovers really like to tinker and tappet adjustment is almost a religous ritual for many.
2. Improve the oil filter - I machined a new filter housing which uses a standard modern cartridge type filter available at Advance. This is not a screw on car type filter - that doesn’t look right, so I have a finned aluminum housing I made.
3. Aesthetically, and this was very important to me being an industrial designer- keep the “vintage” and “Enfield” cues strong. I thought I would pick up from the last Enfield big twin- the Interceptor. The rounded profile of the front of the crankcase and pleasingly smooth and gently radiused forms of the castings and the cooling fins on the side of the wet sump. A wet sump simplifies matters and also ties in with the last Enfield big twin- the Interceptor Mark 2, which also had a wet sump.
4. I love the external copper oil pipes that are such beautiful visual elements on vintage engines, so I decided to incorporate that as well. This also helps to keep the oil cool as it travels through them, exposed to the air.
5. Keep the frame mods to a minimum and again keep the “vintage” feel going by keeping the single down tube- the Enfield big twins of yore had single down tube frames and handled well. The look of the “vintage V twin” I think is the very simple and elegantly “cradled” engine between two tubes- front sloping forward and rear sloping back.
