The DVD for the TTXGP 2009 just arrived at my house. Very exciting stuff. Very much recommended if you're interested in this historic event. If you don't know about the TTXGP, well, browse back in time in the EV Racing forum on this site for reports from June 2009.

The DVD is on two discs (that's the version I bought) .. disc 1 is the race plus a couple extras .. disc 2 is all extras.

The race part is in the style of live TV coverage (and, probably, is the live TV coverage). It jumps back and forth from bike to bike, has a commentator providing both color and standing all through the race, and does a great job following the bikes as they go around the Isle of Man. It includes shots from the side of the road, from an overhead helicopter, and from on-board cameras on the bikes. It gave me a wholly different appreciation for this race to watch it this way.

The extras include ... interviews with racers ... full length on-board video for most of the bikes ... a post-race Q&A session ... clips from TV broadcasts ... and more. The on-board video recordings, well, I only watched one of them because it's the full 34 minutes it took that bike to get around the course and I can only imagine what it would take to watch ALL the onboard video's.

Very good, very worthwhile ... http://eGrandPrix.tv and http://eGrandPrix.com

Infineon Raceway will also host the best in motorcycle road-course racing at the AMA Motorcycle Sonoma Showdown, May 14-16. The weekend will also feature Supermoto, as well as the first-ever electric motorcycle race in the Sonoma Valley with the TTXGP U.S. Championship.

I'll note that Infineon is in the SF Bay Area and that the bulk of the U.S. Electric Motorcycle industry is here in the SF Bay Area or within a short drive. That includes Thunderstruck Motors, Electric Motorsport, Lightning Motors, Mission Motors, Zero Motorcycles and a little further afield Motoczyz, Brammo and Barefoot motors are all in Oregon and were TTXGP participants.

That should be a very interesting race. However it's also very close to the TT race on the Isle of Man so I wonder which teams will choose to compete in what race?

Its been a long wait, but finally we can release the rules for TTXGP 2010.

We have tried to keep the freedom for innovation and experimentation but have also adopted some lessons we learnt from 2009.

These technical rules are the same for all the TTXGP championships. Additional supplementary rules for the series and venue will be released in due course. These together form the body of rules for TTXGP 2010.

Our thanks goes to the TTXGP Technical Panel for pulling together in 2009 and helping get these out.

Any supplementary regulations, final instructions or clarifications will be notified to registered teams, as well as being posted on eGrandPrix.com.

The entry process for teams is also coming as we revamp the TTXGP website with a new system.

Lots more to come so stay tuned.

Team TTXGP.

On-bike footage from the bike Roy Richardsons rode for Brammo at the TTXGP

This article is by someone who is with Richard Hatfield on the Bonneville Salt Flats. Richard is the owner/inventor running Lightning Motors, and is also involved with the Killacycle team. He's built very fast bike that he had intended to bring to the TTXGP race (but it didn't get together in time) and they currently have it in Utah on the salt flats. I had talked with Richard in August about the bike and have a few pictures.

The bike is using a pack built of A123systems cells, and is powered by a motor salvaged from an EV1. It's a massive motor. Interestingly it has two separate liquid cooling systems in the motor. Richard believes the bike will do over 200 mile/hr.

In yesterdays installment it was revealed that the Bonneville people declared their dustbin style fairing was illegal. That left them scrambling to mount a normal Ducati style fairing.

The following are the pictures I took at the EV Rally of this motorcycle. The fairing on the bike is the one that was declared illegal.

An interesting view on torque on high end motorcycles by someone who knows far more about this than I do:

Local TV news report on the Power of DC 2009 put on by the Electric Vehicle Association of Greater Washington, DC.

Here we are having way too much fun testing out some new batteries.

It is a local IHRA track that is only a step better than the outlaw tracks in the area, but they do run a safe show and it is really close to us.

We got there before the crowds (yes it will be PACKED later) and did some test runs.

Fun stuff!
