Quick Bullet speed/weight test.










So all those questions about taking a pound or two off their bullet's weight to gain some speed???



FORGET IT!

Coincidentally I was just reading about weight loss for runners. It seems that for every pound lost a runners time per mile will drop by 2 seconds which hardly seems worth the effort. I would think weight loss for a bike is pretty negligible in increasing speed and acceleration as now proven by Scalyback.

Top speed difference will be negligible, acceleration - might just be noticeable.
Where you will see a difference is in chuckability (that's a technical term)

Malcolm Simmons ex speedway rider once said that he could never understand why some riders spent time and money shaving a bit of weight off the bike here and there when all they needed to do was not eat before a meeting. That said I have lost 2 stone in the last year and I'm sure that has made a big difference in acceleration. No data to back it up but just my gut feeling, pun intended!

It's an Enfield you need a calendar not a stop watch.

As Pete F intimates (given certain constants (like grip)) reducing mass may improve acceleration, deceleration (ie braking) and turning but will have little, if any, effect upon ultimate top speed - unless we're talking top speed within a measured distance.

Indeed, adding mass (in the form of an effective fairing) may improve ultimate top speed (at the expense of the other items).



Whether any of this is measurable will depend upon the magnitude of the improvement, the accuracy of the measuring device(s) and the ability of the rider to be absolutely consistent.



TBH honest - unless you go really mad - it's irrelevant away from the race track, anyway.

The Kawasaki I have comes in two versions with or without a fairing I have the faired version which is heavier, but according to the book it is also slightly faster

Confucious say: If you want speed, buy Honda.

Since removing the army crash bar, rear panniers and top box Bertie accelerates noticably quicker, he has lost the weight of a child and wind resistance is a lot less.
