Hi Guys I am from Australia and have an MNR Vortx with a Yamaha R1 engine. I have a Muffett Differential from the UK. It has LSD, drop gears to change the final drive and a built in reverse. Expensive but well worth it when you consider everything is in one neat package. Pic of diff on my blog page gallery. >http://www.vortx.bigblog.com.au PS. I know of two MNR's that have been sold to the US but I'm not sure if they were BECs or not.
