A great read!   ;)

Brammo Forum / Re: Brammo Empulse history

Talk about a walk down memory lane! Mostly factual with any one of these points deserving of a chapter's worth of additional explanation and backstory.  The main point I take issue with is that the Empulse died when I left.  It was really when Polaris chose to shutdown the Victory brand to put all their focus on building Indian as a "heritage brand" to compete with HD.  One final point is that the Empulse remained a "first generation product" in regards to the powertrain (the battery, developed by Brammo, reached 2nd generation in the Victory Empulse TT) and we were never able to make improvements to the gearbox that may have pointed the way to an alternative to the ubiquitous direct-drive system that dominates today (and at Zero).  In the end, we just ran out of time and money...

:o  Do you think it will be a professional/MotoAmerica thing or club-level?

I think the dream is MotoAmerica. But, you know, a lot of negotiations and talks would have to go well. Ideally it would be open class electric and gas bikes together.

That would certainly be pretty darn cool.  I'll keep my fingers crossed!  Let me know if there's any way I can help...

Oh, I have a feeling something is in the works now that there are Moto-E bikes that can't be used for Moto-E.

Oof, that poor orange bike can't catch a break. Glad everyone is safe, and congratulations on the impressive lap time! Really good photos and video, too. Thank you for posting these updates.

Heh... yeah, it's been a rough season for the factory bike (and owner).  It was great to see us make some progress on the lap times though to give me some encouragement to keep going.  Glad that you're enjoying the updates.  Kenyon also set a PB on his Zero SR/F - a 1:39.0, so progress on the production bike side as well. 

We need an Energica in this photo as well!  Maybe next year?

Part III of Racing Laguna is up!  Check it out... spills and thrills...

It just occurred to me that it will be interesting to see a side-by-side comparison (hopefully published by someone other than the Noob  ::) ) between the Energica Experia and the DSR/X. Both models seem quite comparable in both features, weight, power and price - if not styling and the ability to DC charge.

I spent some time crunching some numbers yesterday. The DSR/X's base price is $24,495 and the Experia's Launch Edition (all the bells and whistles) price is $25,880. But the DSR/X at that price doesn't come with anything. No racks, no luggage, blah blah blah. I added those, the Rapid Charger, Scott Harkless' Dual J mod, chain kit, and windscreen to get them as similar as I could. This is what I came up with:

Some corrections, Morgan.  Understood that you're favoring the Experia, which is your prerogative.  The DSR/X is not a "launch edition" - it's just one version, currently in serial production and shipping to dealers.  Looking forward to the skeptics throwing a leg over and trying for themselves.  It's impossible to convince people how good this bike really is (including the journalists) until they test ride it.  The DSR/X has off-road capabilities that no other electric motorcycle offers with almost 10 inches of ground clearance, 7.5" of travel, 19" front wheel, and the most advanced off-road traction control and ABS that Bosch currently offers with their 10.3ME system.  All other electric motorcycles, including our SR/F and SR/S are using the 9 series system.  It also has 28 liters (7.4 gallons) of on-board storage WITHOUT any accessory luggage.  For this reason, we believe this is the first true electric adventure bike vs. other bikes that would be classified as "sport" or "sport touring" motorcycles.  Most owners may not use the bike's offroad capabilities, but this is no different from other motorcycles in this category (or other categories for this matter). 

Richard, the DSR/X comes with a park mode which is a slow speed reverse and forward creep that you can quickly toggle back and forth between. 

The belt is rated for full off-road use and there was not a single issue with a belt in 100s of journalist and dealer rides.  The new belt system is over 2.5X stronger than the belt used on the SR/F and SR/S, which is in turn much stronger than that used on the older DSR platform.  The rear sprocket is a ported sprocket, which allows debris to escape, and there are additional belt guards in place to prevent the debris from finding its way in to begin with.  But... we do have a chain kit if someone really can't be convinced.  All our test riders, which race MX and hare scrambles on weekends, choose the belt drive when testing the bike. 

The windscreen is certainly included in the price and is fully adjustable, so it will work for most riders.  The touring screen tends to be preferred by riders over 6' tall. 

I learned at the launch event in Sicily from a journalist that spent significant time on bikes with CCS/DCFC that the 22kW charge power is overstated as he mentioned in most cases his bike would only charge at 4-6kW due to battery temperature limits.  So... CCS certainly expands the available infrastructure (by ~10%) one can use and provides higher peaks in ideal conditions, but I wonder if this inconvenient truth about other factors tends to be left out of other OEs marketing talking points...

Carry on...  ;)

Hi Brian, I've seen guys do multiple drag runs or hill climbs without charging and with the lower voltage of each run their time slips more and more.

Do you feel that is happening towards the end of the races?  IOW the gas bikes are able to pull away just a little bit more at the end?

We see about a 10% drop in peak power by the end of the race, but the torque remains consistent, so really only top speed suffers.  This is happening while the rider and tires are improving, so the drop of in lap times is often pretty minimal.  For Nick, on his customer Lightfighter, he's typically running his fastest lap on the last lap of the race.  His bike is a bit detuned to run in twins classes, so the drop in bus voltage is much less noticeable.  He's also still figuring out what works for him on the bike from a set-up perspective.

Hey Brian, good seeing you and Troy this past weekend. I wanted to share the photos I took of the LightFighter, some in action. I think you'll be pleased with image #7111 in particular. https://drive.google.com/drive/folders/1-8gRP2tcG2cDt1YRdw-6X6IwegJIi9u2?usp=sharing

And yes, you're free to use any of those however you wish.

Great seeing you out there as well and thank you for the photos!  We had an up and down weekend starting with a crash on Friday, but have a few positive take-aways.  It was certainly fun watching Stefano and Troy duke it out and congrats to Energica for taking the win.  Troy had tried to shake Mesa in the first couple of laps and couldn't, so he thought he'd tail him to see if he could learn from him and maybe draft him to the line.  Unfortunately, it back fired as a bagger crashed in the corkscrew, the red flag came out, and they called the race result based on the prior lap.  Oh well.  We'll have another crack at Laguna for the AHRMA weekend in July.  Would be great to see you again then!

Oof, I didn't realize there was a crash. Glad everyone is ok and the bike was salvageable. Since I'm just over the hill from Seca I might pop by.

Yeah, my previous blog post I apparently didn't post here, but you can find it here if you want the gory details: https://www.lightfighter-racing.com/post/things-go-a-little-sideways

Here's a video from a following bike.  You'll see Troy zoom through on the left at the start, move up into second place a couple of corners later, and then exit stage right in the first long left hander...
