Many times in the past I witnessed discussions about the pro´s and con´s concerning Norvins. One of the better reasons against the convertion was always: "It´s heavier than the standard Vincent." Only today I decided to find it out. As I am assembling my engine at
present and are planning to better springing and damping of my Norvin, I wanted to find the correct values for spring rates and damping
front and rear. Therefor, I weighed my frame wheel by wheel with a good platform scale, by hanging the other wheel in its centreline.
Thereafter, I put my engine (cases with flywheels in) plus all other loose engine parts on the scale. Finally, the rest, consisting of silencer,
battery, footrests and some other small parts.
Result: Frame complete on wheels: front 50kgs, rear 53kgs
Engine (BS): 77kgs
Rest : 20kgs
Total dry weight : 200 kgs
Now you can compare this to any modern 1000cc- motorcycle, 4, 3, or 2-cylinder: not bad for a 53-year old bike, and: 6 kgs less than the
standard Rapide!
From my first riding experiences on it last year and from what I am expecting from the Maxton-modifications to the roadholders and girlings on the rear, I am sure, it will be a pleasure to ride!
