Empulse White Noise Racer
BrammoBrian:
As I reported in my write-up from Miller, I half-way converted my 2014 street Empulse R to an eSuperSport race bike when my HVR bike broke in Race 1. When I got the bike back to the shop, the prudent and logical thing would have been to convert it back for street duty, especially because I won't be attending Barber. :( Being neither prudent or logical, however, I decided to keep going with the conversion from street bike to eSuperSport racer...
Here's a couple of photos of the work in progress...

"White Noise" in process:
So far, I've lightened up the wheelset by using a 4.5" Aluminum Marchesini rear wheel we had from the Isle of Man program in 2009 and a front wheel from the new Victory Empulse TT. I'm still planning on running a single caliper and disc on the front based on the performance at Miller and the weight savings (roughly 5lbs).
I've also removed the on-board charger underneath the seat, which pulls 12.3 lbs out of the bike. It's not a simple task as you end up having to remove the entire seat subframe, but the weight savings is significant. I've left the main terminals for the B+/B- connection hanging out of what used to be the charge port, and it's my plan to charge with an off-board Manzanita Micro PFC-40. I haven't actually done this yet, so I'll report back on how well (or IF) that works out.
I'll post some progress photos as I have time. I'm hoping to get down around 420lbs for the complete bike without resorting to anything a "normal" racer wouldn't be willing to do with their bike.

This looks amazing, Brian. Looking forward to hearing about whether the off-board charger works. Performance figures would be nice to see, too.
BrammoBrian:
Of course, any race bike needs rear sets. Especially true for the Empulse where the packaging of the motor and gearbox required a bit wider placement of the foot pegs than a typical bike. The chassis begs you to crank it over, so better to get the hard parts out of the way. Luckily, Woodcraft has a great fully adjustable and surprisingly affordable option available...
It's true that you lose the kickstand, but that's more weight saved (heavy steel knuckle assembly) and race bikes don't have kick stands anyway... 8)
I also love being able to move the shift linkage to a GP shift configuration, which I strongly prefer for the track.
Consultec:
Nice. I'm working on doing some custom fiber layout..

A couple other mods I'm considering:
I really like the idea of a full length belly pan for fluid capture on a race bike sharing the track with others. I bought a vintage belly pan from Airtech Streamlining for my HVR bike and liked how it turned out, so I'm thinking of picking up another for this bike.
Here it is mocked up. It would most likely be painted white to match...
I'm also considering replacing the stock radiator with the same KTM 690 unit I used on the HVR and moving it to the same location, which you can see in the photo above. You probably couldn't do this on a 2013 bike based on the location of the VCU, but looks like it could work on the '14 bikes.
