Over on the Brammo Owners Forum, the regulars were dissecting the picture, above, of the Empulse RR dashboard taken last weekend during Brammo’s triumphant return to the world of electric motorcycle road racing. What is the big number “3” for? Is the “1.58.8” the lap time? Does the “45” represent miles per hour or perhaps state of charge of the battery?
Thank goodness that Brian Wismann, Brammo Director of Product Development, dropped in to clear things up:
You got it mostly figured out. The GPS timing is accurate within about 50ft of the start/finish, so the time displayed for the previous lap is +/- .2s. This photo was obviously either from one of the practices or maybe the first race based on the time displayed there. The 47 is the speed and you can see the motor rev counter above it. The 72 is just indicating the minutes of data acquisition logging still available before the internal memory runs out. This system has been instrumental (ha!) in understanding the effects of changes to the system and ultimately bike performance.
RUNLA = Run lap timer. There are various display modes. Best sector time, Best lap time, Last Lap Time, etc, etc… . If there were a problem with the motor or battery, you would see a warning displayed here instead.
Here’s another close up, taken during a later lap:
According to a tweet on Monday morning by Wismann, the Brammo bike was intentionally operating at 85% power. Even at 15% below max, the bike shattered last year’s TTXGP track record, held by the ZeroAgni bike. Kudos to Steve Atlas, rider for this weekend’s races at the A123 Infineon Round of the TTXGP North American Championship series. Not only is he pretty handy with a bike, he’s a marksman with a bottle of champagne:
It’s not clear when we’ll see Brammo next. In about a month, the TTXGP race at the New Hampshire International Speedway at Loudon will be held. A month later, the show returns to the left coast with a race scheduled for Portland International Raceway for July 17, and another the next week at Laguna Seca in Monterey, California. The historic pairing of TTXGP and FIM e-Power at Laguna is a great thing (we hope) and a real “kum-ba-ya” moment which may end up overshadowing anything that happens the week before at PIR. I think it’s a safe bet that we’ll see Brammo at the track in July. Just not clear, yet, which track or tracks it will be.
What is clear is that Brammo’s two wins last weekend ended up winning them 50 points in the race to the championship round, wherever that may end up. LeMans is another joint race with FIM that will occur on September 23 -24. Whether that will serve as the World Championship isn’t clear to me, as there is actually another race that occurs the next month in Australia. This “lack of clarity” is nothing to be alarmed about. If there is one thing I’ve learned during my extensive (irony intended) experience with the sport, it is early in the electric motorcycle racing season and tracks and dates are bound to change.
