Weighed the bike today!

Finally got around to weighing Project Kool-Aid today, since all of this winter's work. The front weighed in at 200#, and the back at 216#. That is a combined total weight of 416 pounds.
The clincher is that the bike was topped off with gas--tank was brim full. At around 6 pounds per gallon, that should put this SH at around 390-ish pounds dry, if the 4.2 gallon capacity can be believed. Near as I can figure, the stock dry weight is purported to be around 424-426, but maybe someone can correct me on that. I was shooting for a final weight of around 400# with this project, so I was pretty happy to say the least. And I still have more to lose with the replacement Shorai battery I will be getting! Figured I would share!

Cool! Thanks for that, I've been wanting to do the same.

I think the stock bike weighed in at around 470lbs. Cliby got his down to around 390lbs, if I remember right… His bike wasn’t naked, and he shed a lot of his weight with high-priced items like a JCM swingarm and Dymag rims.

I think you’d lose some easy weight going to another Honda rim. I believe Tweety or someone posted the weight of the SH’s rims compared to the replacements (CBRs…?) and it was significant.

Kai Ju’s bike was around 430lbs (again: going from memory and I may be way off). I always thought that sounded like a lot given how trick that bike was, but maybe the large replacement radiator was a lot heavier than the ones on the SH…?

I can get easily obsessed with these sort of stats

Dammit... You beat me you bastard!

I'm at 396 dry...

BTW, the fuel capacity is believable, it's actually 16 Liters, so a bit more than 4.2, but unless you intentionally top it off with the bike upright, you end up at around 4.2 Gallons, or 15.8-15.9 Liters...

LOL! The difference being that you can ride your bike for more than an hour! I can really feel the weight difference in how the bike performs, and it even seems pretty well balanced between the front and rear wheels. It is true what they say, lighter IS better! Thanks for the fuel spec, too. I was not sure how exact that really is. I had filled it up on the side stand. Oh, is it true what they say about lighter wheels?

Now I will focus on dyno tuning for the single exhaust. It is close, but running lean through the entire range. Not gonna mess with it though, until I see and A/F graph. This thing has turned out to be a rabid addiction. The sad part is that I do not know what I am pursuing!!

Yep, lighter wheels make a noticable difference...

Tweety’s SH is pure bike porno.

I saw a chart the other day that listed the RC-51 rims at around 10lbs each and the Oz wheels at around 7lbs. I don’t know why, but it seems like I remember the VTR’s being 12.somethinglbs. They say you feel that unsprung weight a lot more.

It’s probably an easy upgrade to the RC-51 rims – I imagine you just need bearings. Ebay prices are around $150-250 per rim. ‘course once you open that can of worms you might as well get the USD front end and JCM swingarm…

426#, wet.

Rode the bike onto the digital shipping scales at work. What ever was in or on the bike when I got there was part of the total weight, (including my thermos of coffee in the tank bag and the other detritus that accumulates in there).

I suppose that I can understand concerns about a bikes weight and the desire to lighten it in order to enhance acceleration, but in the "dollar cost/poundage shed" arena, the point of diminishing returns seems to come early.

Really, who wants to sleep with a runway model? Sure, they're exotic and you don't have to feed 'em but they seem so fragile that if you push 'em a little they might break.

Just remember there are 2 different RC51 wheels. The SP1 (six spoke) and the SP2 (five spoke) and the real difference is that the Sp2 wheel is 1.5 lbs lighter than an Sp1 wheel (for the front).

Two questions on the RC wheels, are they direct bolt on, and do they fit the same size tires as the SH? I am really interested in this angle.

Oh, and if Tweety's bike is bike porno, mine is more the dirty dog-eared mag left on the bus! But I like it, and it is shiny---and light!

All I can say is stay away from them as there are easier and cheaper ways to go. No they are not a bolt on.

The do use the same size tire in the front but the rear is a 6" rim. Also they use an odd ball bearing size (at least in the front- 22mm)

Then there is the fact that they are getting pretty rare so the price is way up there.

By my calculations (based on weighing parts as I replace/remove them), my VTR should be right at or just over 400 lbs wet...... will confirm it with a scale some day......

BTW, the wet weight listings (various mags) I have seen are in the 477 - 480 lb range

And the brake rotors are larger than the Firestorm (320? vs 296mm)

Guess I'll just poop before I ride, then, and save some cash.

But with the Shorai battery in, it should be near to 75 lbs lighter than a wet stocker. Still and improvement. Oh, and in reference to what was said earlier, better to be on a wet, lightweight model any day
