Hey guys,
I am a newcomer to the forum here. I am currently in the process of building a FWD yamaha R1 powered classic mini with my friend James. In December 2007 I purchased a 2003 yamaha R1 motor. Since then we have modified the standard subframe and have fabricated a custom engine frame. We are at the point of sorting out the drivetrain at the moment and getting the diff/sprocket into the car. I have a project website (www.r1manx.com) and plenty of pictures uploaded (www.flickr.com/r1manx) so please feel free to take a look, I am grateful for any advice or constructive criticism regarding the build from people on this forum. Cheers everyone, I can't wait to get her lit!

Ben

Yeah ive been looking at promotive's kits and they look pretty good.
The only thing I don't like is the diff arrangement as it seems overly
engineered. I have heard some good things about their kits and a few have
mentioned torque steer issues but im sure with the right setup and plenty
of patience they could be sorted out. I was originally going to buy the kit,
but my mate offered his help and the use of his lathe so we both thought, why
not build our own FWD R1 mini! I'm always updating the website (www.r1manx.com)
and the photo gallery (www.flickr.com/r1manx) so please feel free to take a look
and any ideas or questions about the build are always welcome.

Cheers

the promotive guys are grassers, which probably explains the chunkiness off their stuff - if it can survive the bashing it will get in grassing, then road use will be a doddle.

Yeh Darren who co owns Pro-Motive races grasstrack and does really well to be honest, he defo knows his stuff and their kits are really well made and the first fwd to be sold on the market.

Ive had the honour to go out in a few of his cars and the blistering fast and his latest demo car is a work of art imo as he made his own cage etc.
