The Place

hi I have just purchased an f1 out fit and I am not sure about the brake system it is all connected and working but the question I would like to aske? is have got to have a handle bar brake system like the f2 bike that I have looked at .I all ready have a double system that I work with my left foot many thank for you help in advance mike

You don't need one on f1's. There is a reason why f1 and f2 rules are different but i cant remember it!

thats simple,F2 are conventional sidecars and F1's are 3 wheeled cars

I remember it well.
LCR had a pathetic "paddock brake" that was useless but complied with the rules they then decided that they didn't want to fit them anymore.
Instead of failing the new LCRs at scrutineering the ACU made a new rule stating that LCR type machines built after (I can't remember the date) did not need the emergency brake. Everyone with a long bike then decided that any long bike was an LCR type machine so they all took the extra brake off.

So a 200bhp bullet does not need a secondary braking mechanism but my 80bhp tricycle needs one.
That makes sense again.

The auxilliary brake on an F2 came from the original F2 rules, when the ACU thought it might be prudent to have two separate brake systems, so if one failed you could slow down with the other system. Where it went wrong was with people making the auxilliary system good enough to pass scrutineering, but of little use on the track. The "dual system" on the foot pedal has limitations to it working efficiently, especially if it's poorly designed. The "F1" lobby, many years ago, were able convince the FIM that it was safe to have one pedal working the brakes and the ACU followed suit for F1's. A bit like how they convinced the FIM that side operated suspension doesn't move its axis sideways.

For F1 lobby read LCR and the only reason the ACU changed the rule was because LCR stopped fitting the brake.

The secondary brake on short bikes is now a waste of money and time. Even when the said brake was a proper handlebar brake ( like on the Iresons) it was still useless unless it was used constantly.
