Wow, what a jerk. Just looking at the tires and the expensive grips on it, the owner obviously cared about it and took care of it.

Vin was ground off, no plate on the thing, so I guess reporting it was probably a lost cause. Hopefully the owner drives by and sees it, then thinks to himself good lord I hope the insurance company doesn't find it, because it's hosed. So what happens now? Are they going to collect the bike and scrap it?

So I said to my girlfriend, "Ha, look at the dude learning to ride, why is he doing it so late I wonder" God, I could use so many parts from that bike. Looks like an f2 to me.

That's an awesome restomod, but I think the front fairing should've been simpler to go with the rest of the bike. The angular Duc piece isn't working for me.

It kinda reminds me of the RZ350 customs the UK and AUS scenese were fond of a few years ago - you'd put on an R6 front end, an RGV250 rear, bring the cylinders out to 400cc+, and then somehow forget that the frame holding everything together in the middle was basically made out of Red Vines. Here's a photo of me on an RG250 race bike with a TZR250 2MY front and rear from a few years ago. I vaguely remember there being a complete RZ250 engine in the frame, but no idea where the bodywork is from.  e: Wow, those leathers make my butt look enormous.

Got my VFR on a dyno. Same dyno and conditions as last year. Changes I have made include the left exit exhaust. I lost 3hp(80hp now) and it's running a bit rich so time to take the bike to Wheelsmith racing, aka. factory pro. http://youtu.be/lkRotx2rTZA and I found my neighbor's dad at the dyno day with his turbo zx14. http://youtu.be/Un357DNy6a0 228hp!

I've never seen dyno runs being done anywhere without being strapped down, for both safety and for traction. Without strapping it down, you're only testing the interface between the tyre and the dyno wheel, not the power being delivered to the rear wheel, and last I checked the dyno wheels didn't look anything like a road surface.

Ziploc posted:An electric bike with a clutch and gear shift? I like the mechanical act of shifting gears too, but I'm not clear on why an electric bike needs a traditional transmission or clutch. The motor doesn't stall when you're moving slowly or getting started, so you don't need a clutch, and with the incredibly wide "power band" all you really need is a direct drive, maybe with the option for an overdrive if you want to save power on the highway. A simple planetary gearset and a little bit of electronic voodoo that unloads the drivetrain before shifting could do that just fine, and is all any decent EV should need. I mean maybe if you were trying to make a 220mph superbike you'd run into motor saturation (I think that's what it's called?) at the higher speeds and need a set of gears, but I don't think it'd be necessary to have more than the direct drive and overdrive for the 99% of riding that is under 80 miles an hour.

We're very much still in those beginning awkward stages of electric bike development that everyone will look back on and say "why the hell did they do that?". The shiftable electric bike is one of those things. My opinion is you just have to let consumers and manufacturers get it out of their systems.

They're doing it for the sake of "Just like your petrol bike!" but they're about as useful as a chocolate teapot. Electric motors do reach peak efficiency at certain RPMs, but the difference is negligible and offset almost perfectly by the extra drag and weight of a gear box. I think the only thing that might turn out useful is maybe an overdrive for highway use, which you could do with a compact little planetary set and dog clutch.

The way it was explained to me, when I spoke to one of Brammo's engineers last year at the Laguna Seca GP round, was that having the gear box allowed for a lower RPM when cruising at higher speeds. With a direct drive the speed of the bike is always going to be directly related to the speed of the motor, meaning a considerable difference in range when going 35 mph vs 75 mph whereas in their setup the gearing can be used to reduce the RPM at higher speeds and get better range. Also wheelies.

Also wheelies. Yeah, but that's exactly what I said about having a direct drive and an overdrive. Direct drive for in-town and sport riding, overdrive for highway use. The only real reason that we all have 5+ speeds instead of two is because gas engines have a comparatively narrow band of highest efficiency and best power. If your motorcycle engine could start turning the wheel at zero RPM and produced 100% of its rated power at that speed, there'd be no real reason to ever take it out of its highest gear.

Well, you still have the torque multiplication to take into account. In lower gears, you get way more torque at the wheel compared to at the crank. Whether or not that makes any difference on an electric bike remains to be seen, but it's a valid benefit of having a gearbox. With a combustion engine, it's 100% needed, not necessarily so with an electric motor.

I can confirm the Vectrix electric scooter is scandalously wheelie-capable though. Guessing it's weight distribution of the batteries.
