My two cents. Just some constructive feedback.
The rules for Sportsman/LE should be updated to reflect the technology gap between current bikes and the intent of the class. If the 10 or 12 year gap continues as it traditionally has the Sportsman or LE classes will cease to be what they were originally intended to be. 2003-2005 is the start of what I'd consider the modern sport bike era with sophisticated fuel injection, inverted forks, radial brakes, etc, etc.
Even without any rule changes the 2016 LE season would see 2004 ZX10Rs, 2004 CBR1000RRs and 2004 R1s eligible for LE. Those bikes are not "Lost Era" in the sense that the class is intended to be. They are still competitive in the Superbike classes with current bikes. Changing to a 10 year delay would mean that Luke's Superbike is LE eligible as of now. Seems a little silly to me. I think it would be prudent to consider a future rule change to clearly establish that Lost Era bikes are actually from a Lost Era.
