Motorcycle: Front Brake required?

[tylerm]

I have a couple LSR bikes I have run at Speed Week the last few years, and I want to bring one (or both) of them to some ECTA meets in 2013. Neither has a front brake. Is one required to race at Wilmington? How long is the shut down? I couldn't find a course map on the ECTA website. Thanks in advance!

Whoa is more important than go!  Especially when the unexpected happens!

Tyler.
The short answer is that over 175 mph front brakes are required.

We ran 189 at the Texas Mile with the 1000 in 05... in Bonneville trim... too much weight, no front brake...  made for a nice blue back brake after it cooled enough that you couldn't feel it from a foot or so away.  Rob was only in the dirt a couple of times 
I would suggest putting on the front brake for any of the mile events.

From AirNav;

"Runway 4R/22L
Dimensions:  9000 x 150 ft. / 2743 x 46 m
HAS 200 FT PAVED AREA EACH END.
Surface:  concrete/grooved, in fair condition "

The starting line is right at the north end of runway. The mentioned 200' run off apron is staging area. Timing is the last 132' of the mile. There is .704 mile of shutdown plus the 200' runoff apron.

Full width drum vs. disc:
Drum has inherently stronger wheel with shorter spokes, narrower aero profile, no parasitic drag
Disc needs less contact area for the same BTU dump (higher pressure), faster cooling of fraction surfaces, only some calipers can be completely floated for no-drag in release mode

Thanks guys. The SCTA classes are 750cc A-VG and 1350 cc A-VF. The 750 (1955 Triumph) has no front brake, drum rear. Ran 120.9 at Bonneville.. so far. The 1350 is a dual-engine 1955 Triumph, no front brake, disc rear. Ran 129 mph so far, only have 12 or so runs on it as of yet, should be able to up that a decent amount.
