The Grand Prix Commission met at Misano to agree a couple of steps on the long road towards creating a single, unified MotoGP class from 2016.

The four parties to the GPC agreed that the minimum weight in the MotoGP class would be reduced from 160kg to 158kg, and agreed to freeze development of the software for all Factory Option class bikes from 30th June 2015.

From that point on, work will switch to the spec, or unified software, ready for the start of 2016.

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.

MotoGP riders are to get some help with braking. From Mugello onward, all riders will be able to choose once again between running 320mm and 340mm brake discs on the front wheel. Use of the 340mm discs had been made compulsory at Motegi for safety reasons, but now, they will be available at all circuits.

The 320mm brake discs had been made compulsory at the end of the 2011 season, in an effort to cut costs. At that point, teams were free to choose from multiple sizes and masses of brake disc, meaning they were forced to purchase and transport sizeable numbers of discs to each race, while only using one or two sizes. Limiting choice was meant to rationalize the process, and cut costs for the teams.

Unfortunately, the compulsory brake disc size was imposed at the same time as bike capacity and weight were increased. In 2012, the first year of the restrictions, capacity of MotoGP machines was increased to 1000cc, and weights were increased to 157kg, and a year later to 160kg. With more power and nearly 7% more weight, braking forces were growing very large once again.

One of the more intriguing things about spending a few years in a racing paddock is watching people grow and mature. Young riders come in to the Grand Prix paddock as exuberant 15 and 16-year-olds, certainly with the anachronistic maturity of all dedicated sportsmen and women; but still clearly young teenagers, that explosive mixture of energy, hormones, and sheer joy driving them into paroxysms of hyperactivity. A few years later, those young boys (and now girls as well) turn into young men, and a fuller, more mature personality emerges.

Such is the case with Scott Redding. Three years ago, when he first moved to Moto2, he was still a teenager with an impish grin on his face, looking like he was either planning trouble, or just returning from it. At the launch of the Marc VDS Racing program last night, at the Belgian team’s workshop a stone’s throw from Charleroi airport, a different Scott Redding was on display, calmer, more mature, more serious but without having lost his sense of fun. More focused, too.

Redding knows that this year, he is playing for keeps. The goal is to either win the Championship, or go down trying. This is his best chance, perhaps, with the introduction of a combined rider/bike minimum weight removing some of the advantage of the lighter riders, though the new limit of 215kg for both rider and bike still favors riders closer to 60 kg than to 70kg. His preparation has changed, spending the winter in Spain, riding, rather than in the dull English winter, where MX tracks are open on Saturdays and Sundays only, for a couple of hours each day.

Scott Redding is ready to become Moto2 champion. A conversation with the young Englishman follows after the jump.

The weight increase in the MotoGP class introduced for 2012 – from 153kg, as originally agreed when the 2012 regulations were drawn up back in August 2010, to 157kg – has had many repercussions. The addition of 4kg to the 1000cc MotoGP machines has been blamed for causing the chatter that Honda’s RC213V suffers from, and for complicating the pursuit of the ideal weight distribution for both Honda and Yamaha, which the two Japanese factories had spent most of 2011 perfecting ahead of the 2012 MotoGP season.

The decision was taken in a Grand Prix Commission meeting held on December 14th of 2011 in Madrid, and though it drew little comment at the time, once the MotoGP paddock reassembled at Sepang for the first test of the year, some intriguing details started to appear. Crash.net’s Peter McLaren has an excellent reconstruction of the decision process, from which it is clear that the path to adoption the proposal faced was far more complex than usual. It also reveals some of the underlying tensions in both the Grand Prix Commission and the MSMA which will go on to play a major role in the rule-making process for 2013 and beyond.

AMA Pro Racing has  announced a change in  the minimum weight requirements for both the Daytona SportBike and SuperSport classes, biasing the weights to be more of a disadvantage for two-cylinder machines, i.e. Ducati 848 Superbikes. Decreasing both the four and three-cylinder minimum weights by 5 lbs (to 355 lbs & 365 lbs respectively), two-cylinder machines conversely get a 5 lbs increase (to 385 lbs), thus making the spread from four to two cylinders now a total of 30 lbs (it was a 20 lbs difference before this rule change).

The move is presumably to reel in the Ducati 848 race bikes that shocked the paddock with their speed early-on in the season at the Dunlop Test, though in terms of race results, the change in rules seems to be due more because of the domination by Jason DiSalvo, than anything else. The Team Latus Motors Racing racer has won every race thus far this season, with a close finish at the Daytona 200, and a blow-out double at Infineon Raceway.

Confounding though, Ducati’s results in the SuperSport class have been less impressive, with the 8th and 13th being the finishes for the Italian brand at Infineon.

From the official results of World Superbike’s stop at Brno, the FIM has once again determined that twin-cylinder motorcycles, i.e. Ducatis, will get another minimum weight reduction. Averaging more than a five point deficit over the last three WSBK events (Miller Motorsports Park, Misano, and Brno), WSBK rules require that twins be given another 3kg weight reduction, as the rules have been deemed to “favor” the 1000cc 4-cylinder motorcycles too heavily.

After public pressure from Althea Ducati and surely private pressure from Ducati Corse, the FIM has agreed to allow twin-cylinder motorcycles in World Superbike to have a 3kg lower minimum weight allowance. Effective at the Miller Motorsports Park round of WSBK, twins (essentially the Ducati’s) will be allowed a minimum weight of 165kg (363.7lbs), down from the previous 168kg minimum weight allowance. The mode of this change in rules comes about from how the rules were drafted, which allow for a continuous revision of basic components to the rules as the season goes forward. More on that after the jump.
