What is the spline standard used on the 2017 R's
Clearances would be helpful for machining existing standard parts to clear..

I have not confirmed this myself, but the spline is supposed to match a KX250F as well as a YZ450F.

We have an upgrade we've prototyped but developing it further hasn't been at the top of our priority list. I figured I'd post some pics and see if there's interest. If we get enough pre-orders I could quickly finish it up and do a production run.

This conversion would allow you to convert to a 2014 Fast Ace fork or even the newer Showa fork. If you convert to a 2014 fork, you get to use the existing front wheel and brakes which makes it quite a bit more affordable than converting to the Showa fork.

Attached are a few pics of a 2013 DS converted to a 2014 front end. Cost of this setup would run about $1500. I haven't priced out the Showa front end but I estimate it would be closer to $2500 and you'd have a cast wheel, not a spoked wheel.

If this is something you are interested in, email me the details of what you would be looking for at harlan at hollywoodelectrics.com

Ha! Yeah. I mention it not so much for the weight savings but as a testament to the quality of the carbon work. It is very nice.

Transparency is not Zero's strong suit.  Its a disappointment as they should really lead in this area.  Perhaps they will figure that out sooner or later.   But as Zero Apologist (tm) Electronic Terry has pointed out they are a private company and are not required to release those numbers.

Not sure what your beef is with Zero or why you think transparency in sales figures is so important, but there's no need for name calling. Especially Terry who is a huge supporter of the community and one of the most genuine people I've ever met.

Thanks for all the positive replies.

Only one question.... How in the world do they attach it to the plastics when they're melted plastic rivets?

The tank cover attaches easily in only a few minutes without even having to remove the tank from the bike. You simply drill two small holes at the rear of the tank and use a couple of self tapping screws, or rivets if you prefer.

Does the tank cover keep the contents dry in wet weather?

The tank cover is not water tight but it fits to the tank perfectly to minimize water penetration. On the bike you see here in the pics, we've upholstered the tank bag holder for a better seal but alternatively you can use thin piece of weather stripping, or a rubber bulb seal. Its really up to the installer to decide.

That is gorgeous, but I'm with JaimeC. It's not compatible with mounting the Diginow in the tank location, so I can't do it.

When I had my bike wrapped, I had him wrap some of the cheap plastic-looking pieces (rear fender, battery box side covers, even the "reflectors" on the Givi trunk) with a carbon fiber wrap, and it really spruced up the bike. Unfortunately it's just a cheap vinyl wrap and it's not all that durable. I'd pay a fair buck for some real carbon fiber pieces that will look as good as this tank does indefinitely. It's hard to overstate how much those cheap plastic parts drag down the appearance of the bike.

Even if the tank cover is not for you, the carbon fender and seat cowl really add a lot to the look of the bike.

Ok anyone still reading this post go to Zero's Facebook page and watch this bike KILL a supermoto track and pass ICE bikes like they are stalled.  TORQUE!!!

Eeggcellent!!  If Zero started selling this bike and stock Zero's start tearing up tracks and winning races across the country they would get a lot more mainstream attention and buy in...especially for the FX/FXS where the range is not as critical...especially when you have a system that allows you to swap packs quickly under race day conditions (if you have the $$$ for extra bricks and chargers...this is where falling battery prices could REALLY make a difference).

I'm still skeptical that we will ever see a bike like this directly from Zero (at least in the next couple years) due to the fact that they have made many public statements in the past regarding their belief that they are at a good pack voltage balancing power with safety.  But I have a sliver of hope and here's why:

1. Zero collaborated with Hollywood electrics on the bike.  If the custom battery pack they used to enable using the high voltage size 4 controller came from Zero that would increase the likelihood that we might see Zero up the voltage on future bikes.
2. Harlan did the size 6 controller first and then Zero followed offering an official SR.  It doesn't seem like a huge stretch that they would collaborate with Hollywood Electrics to create a test bike for Pikes Peak with plans to offer higher voltage bikes in the future.
3. It wouldn't be the first time Zero increased the pack voltage on their lineup.  While it may be unlikely that they would do something like double the voltage of the pack and change the motor and controller to match, switching to SEVCONs high voltage Gen4 offerings doesn't require a huge leap....current is 116V max...high voltage controllers can handle 150V max.
4. Zero started updating the monolith batteries for older Zero's under warranty and replacing them with ZF12.5 and in at least one case someone posted they got a ZF13 pack.  While I trust that they may have legitimate concerns that the older packs are going to live up to the warranty they may also be taking advantage of the opportunity to clear out stock of older bricks.  And the ZF13 is new for 2016 so if they are trying to clear those out then that offers more hope.  That said there could be many other reasons they are trying to clear out old stock of batteries.  For example, the Power Tank for 2016 is still using the ZF2.8 bricks.  They may keep using the same 29Ah bricks for 2017 (i.e. ZF3.3/ZF6.5/ZF9.8/ZF13) and be planning to up the ZF13 + Power Tank from 15.9 kWh to 16.2 kWh.
5. Increasing pack voltage would allow the flexibility to keep torque at the wheel the same but change the gearing to enable a higher top end and thus make the FX/FXS a lot more competitive. (side note: Don't be fooled by spec sheets.  Using the high voltage controllers offers a bigger increase in performance than may be obvious by just looking at the numbers (e.g. peak current, continuous current etc.).)

It would be really sweet to see Zero update to the high voltage controllers across the lineup.  However, SEVCON is currently not yet offering a size 6 high voltage controller so if they are planning to up the voltage across the lineup they would either be one of the first customers to use it or the transition isn't planned to take place for a couple more years.  I'm not sure how likely it is that they would increase the voltage on some models (i.e. everything but the SR) and not others....I wonder how a high voltage 'Zero S' with a size 4 controller and IPM motor with high temp magnets would compete against the current SR with a size 6 controller??

However, IMO, if they were to start selling this bike traction control is a must.  The FXS is so light that the rear tire is already eager break loose with a quick twist of the wrist.  I can't remember who said it but in one of the videos Zero posted they said that the pikes peak bike couldn't keep traction with the stock tires and they needed to go to really soft slicks to handle all the torque.  I suppose they could gear to keep torque at the wheel the same as the current models and just take advantage of the higher top speed.  Or they could program to keep torque tuned down when RPM is low and take advantage of the extra power when RPM is higher turning the FXS into a wheelie machine.  Although traction control may or may not be all that desirable on the track, if its being used as a commuter I think even the current models could really benefit from it.  I already want an FXS or an FX (or both)....if Zero offered a high voltage FX/FXS I would have a hard time keeping myself from buying one.

The controller we used in this bike is not a high voltage controller. It is running at the same voltage as production Zeros. As I said before, we have not deviated from the production bike much at all.

They may never be sold to the public but what are some of the stats and feel of riding a FXS with a SR motor?  Is it like hoping on the back of a cheetah?  Does it wheelie like a fat man on a kids bike?  If you have a little mustard on your chin from a hot dog will the torque wipe it off for you? 
I wish the road and weather was better for yall at Pike's Peak but still great showing for the electric bikes, and good press.
Keep those Skunk Works projects coming.

Thanks for posting! You can read my race report here: Pikes Peak Race Report

I've included a bunch of pics and some video in the link.

I'll give you a little more technical insight since I'm sure that's what many of you come here for. Our approach was to keep the bike as light as possible and if you take a look at our practice runs, it was working out pretty well. Mark and Marcel were among the fastest bikes up the mountain, only Don Canet and a few liter bikes, beating us. Not bad for a couple of rookies! With the very limited practice we are allowed, there no doubt that a few years of experience goes a long way at Pikes Peak.

The trick with an electric race bike is sustained performance for the duration of the race. Our system was pretty well balanced allowing the motor, controller and batteries to all work together and hopefully arrive at the top with little battery in about 10 minutes. This would mean we'd be operating at about a 6C discharge, with 6.5kWh of battery, that's almost 40kW of power average. Although an SR controller would make the bikes a lot of fun, I don't think it would have benefitted us in this race because we were already operating at the limits of the batteries and motor, and it would have added a bit of weight.

In the end, the weather was not on our side. Rain the night before left water and ice on the road. Mark ended up crashing, and although he picked up the bike and kept going, he lost a lot of time and dropped a few places behind the other electric bikes. We were really aiming for the mid-10s and I think we could have hit that target so it was a bit disappointing, but we beat our previous record by a huge margin and beat the other production EV, a Tesla Model S, so all was not lost.

Maybe we'll be back next year to take another shot. That remains to be seen. It's a lot of work, time and money for 10 minutes of racing, but its a very special event.

Thanks to all of you who have enthusiastically supported our race efforts. We still have several of our limited edition 2016 Pikes Peak shirts available. Give us a ring at the shop to order one, only $30!
