The news that 340mm carbon brake discs are to be allowed once again in MotoGP has rekindled a debate that has been going on behind the scenes for some time.

The move to allow the discs at all tracks, and not just Motegi where they are already compulsory, has come as both power and weight of the MotoGP machines has grown over the past three years. But the real solution lies in reducing the minimum weight.

There was a certain irony in the moment chosen by the Grand Prix Commission to ban carbon discs larger than 320mm. The move – made for reason of cost savings and rationalization – came just as MotoGP was to return to 1000cc, meaning the bikes were about to reach higher top speeds.

Compounding the problem, the minimum weight was also increased. The initial proposal was to raise the minimum from 150kg, the weight of the old 800cc machines, to 153kg. However, to make life easier for the CRT machines, the weight limit was raised even further, in two steps, to 157kg in 2012 and 160kg in 2013.

In the space of two years, engine capacity had been increased by 25%, leading to a power increase of around 10%, while weight had also been increased by nearly 7%. It was a recipe for brake problems, and that is precisely what occurred.

As the MotoGP circus descends upon the charming French town of Le Mans this weekend, there is one question at the front of everybody’s minds: can he do it? Can Marc Marquez continue his incredible string of poles and victories by winning at Le Mans?

On the evidence of the 2014 season so far, you would have to say he can. But Le Mans is a different circuit, and one where a gaggle of Yamaha riders have gone well in the past. This could possibly be the first race since Qatar where Marquez is made to work for it.

Marquez has a lot going for him in France. Leaving aside his form – a perfect record of poles and wins this year, as well as being fastest in over half the sessions of free practice so far – the track looks to play to the Honda’s strengths, on paper at least.

The stop-and-go nature of the Le Mans track sees the bikes spend a lot of time under hard acceleration, with slower corners needing hard braking. The Honda’s ‘V’ approach to the corners – brake late, turn hard, stand the bike up quickly and get on the gas – seems to be a much better fit to the Le Mans circuit than Yamaha’s ‘U’ style – brake early, enter faster, carry more corner speed and smoothly wind on the throttle.

And yet Yamaha riders have won four of the last six races at the circuit. Jorge Lorenzo has won the French Grand Prix at Le Mans three times, and each time with a very comfortable margin over his competitors. Valentino Rossi has won here twice on a Yamaha, in 2005 and 2008, and finished second behind Lorenzo in 2010.

It’s even a track where Colin Edwards has shone in the past on a Yamaha – and where perhaps he can do well once again, despite hating the current Yamaha chassis he is riding at Forward Yamaha. This is the first in a series of circuits where Yamaha riders have dominated in the past.

If Jorge Lorenzo and Valentino Rossi want to start fighting back against the might of Marquez, Le Mans is as good a place to start as any.
