Erin Okonek and Mike Garcia are recording record breaking speeds at the Bonneville Motorcycle Speed Trials this week. The turbo Busa is approaching 250 mph and... the NA bike is approaching 225 mph as they throw salt rooster tails. Congrats to them and the whole crew at Sims Motorsports and Paramount Speed and Mike Garcia Racing. We are remotely supporting the effort with MoTeC tweaks from our base at Electron Speed. See more

Great job Erin & Mike!

Finishing up some service on this RD400 #1kickcoldstart

Just finished ZRX1100, it got a full engine overhaul which included new high compression big bore pistons, ported cylinder head by Richard, mild camshafts, hardwelded rocker arms and rejetted the carburetors to match. We must say it runs like a new bike and pulls pretty hard!
