R1 Seven

Hard to believe it has been 10 years already. I was there with my recently completed Locost. A fun weekend for sure!

I'm not sure, honestly. I thought that I ordered them all. Is that one a different part number? Maybe I overlooked it.

Aaron, That is a bummer. For reference, I logged around 13 track weekends and a few autocross events on the car on that clutch and Barnett clutch kit. Add however much you have been driving it, and that is how long it lasted.

Aaron, What oil are you currently running in the R1? When I had the car, the clutch would slip when I tried non-motorcycle oils in it. I went with Yamalube exclusively, and it worked flawlessly from then on. Hope this helps,

The car is sold. Thank you for your interest. I think it should be going to a good home.

***Sale Pending***

Price reduced to $15,000

There have been several folks that have said they wanted it over the years...hopefully one of them still does.

Thanks. I don't *want* to sell it, but we can't hold on to everything, it is not getting much use, and future projects beckon. Croc - There were some variants after this model year engine that made 180hp from the factory.

For sale is a 2007 Locost 7 powered by a Yamaha R1 Motorcycle engine. The car is based on a CMC frame that has been extensively modified for both safety and performance. The chassis has the dimensions of the original “book” Locost design. Below is a list of features on the car: 2003 R1 Engine (160HP Fuel Injection) 6-speed Sequential Gearbox (Bike Transmission) Toyota 10-Bolt Rear End with TRD Limited Slip (3.31:1 Gear) GAZ Coilovers and Eibach Springs Wilwood Calipers Front and Rear Twin Master Cylinders w/Cockpit Bias Adjuster Full Roll Cage Kirkey Race Seats and 5-Point Harnesses JAZ 8 gallon Custom Fuel Cell Two Sets of Wheels http://i746.photobucket.com/albums/xx109/RexRacer19/FrontQuarter.jpg This car was built by had over the course of several years. Both the front and rear suspensions were redesigned and built to work with the components used. The entire build was documented from start to finish here: http://www.underwood-racing.com/project_seven.htm The “Construction” tab has all the build details. You can also read about the development of the car and see videos of it in action. The car was built to be a track/autocross car specifically, and is not street legal. It could be made that way with some additional lighting and wiring. It has been a great track car, and has competed in several time trial events in the Southeast, as well as participating in the very first Grassroots Motorsports Ultimate Track Car Challenge. It even earned the SPU class championship with the Tarheel Sports Car Club in 2008. It is fast, easy to drive, easy to maintain, and very easy on consumable parts. http://i746.photobucket.com/albums/xx109/RexRacer19/RearQuarter.jpg http://i746.photobucket.com/albums/xx109/RexRacer19/Engine.jpg A full gallery documenting the current condition of the car can be found here: http://s746.photobucket.com/albums/xx109/RexRacer19/R1%20Locost%20For%20Sale/ ***Sold*** For additional information please email to supratt(at)cox(dot)net.

My friends George and Stefan will be there racing their Series 1 this weekend. It is the red #37. Stop by and talk with them about their cars...nice folks.

Hey Bruce, The car is looking great! I really like the new wheels.

That is the same setup I am running and it has been great so far. Just be sure to run motorcycle specific oil, or you may have some clutch slippage under hard acceleration.
