Racy eco-GP bike leaked

2009-06-01 08:35
Two weeks ahead of the inaugural  zero-emissions TTX Grand Prix on the Isle of Man, the Brammo Enertia TTR has been leaked onto the web. This happened only days after Brammo execs announced that they would be entering two TTR models in the TTXGP event, greatly upping the competitive ante.

The TTR is a racy version of the Enertia eletric motorcycle which will start production later this year, and on 12 June it will take to the track alongside the EV-ORR  and “fastest-electric-bike-in-the-world” Mission One.

Powerful batteries are the most important element of electric bikes and the TTR relies on a chunky 8kWh battery pack (twice the capacity of the Zero S. This large capacity will come in handy when the TTR rips through the Mountain Course which winds its way for 60.72km through the Isle of Man’s hills.

The Brammo Enertia TTR race bikes are based on the same Enertia production model that consumers will be able to buy from later this year. The racy contender started as the production Enertia with its extruded aluminium frame rails, distinctive flowing bodywork, and unique battery mounting system as the basis. Where necessary, key components were then “overvolved” for the demands of racing and super-high performance.

As part of the development plan for the TTXGP, AMA champion Aaron Gobert was the first to ride the Brammo Enertia TTR race bike on a racetrack. According to Brammo, Gobert was "blown away" by the bike’s performance and handling and had this to say: “The Enertia TTR was unreal and I was amazed at how light the bike feels. Being so quiet and with no vibration, there was no fighting the motorcycle. It’s incredible going through a corner and one of the easiest to ride bikes I’ve ever experienced.”

The TTXGP is the world’s first “zero carbon” Grand Prix, and is scheduled for 12 June 2009 on the Isle of Man’s Mountain Course as part of the historic Isle of Man TT. This race will provide a fresh international platform for electric bikes and the technology behind them.

This alternative GP is aimed at driving low-carbon technological innovation forward by proving that clean-emission transport technologies have matured and can be fun, fast and exciting. Although it (probably) started off as a bit of a PR stunt, the TTXGP has now developed into a full-on race that will showcase the electric bikes as a real-world alternative to those that run on fossil fuels.
