1999 Aprilia RS250 Challenge – the 2-stroke racer

apriliaRS250-1999

A beautiful 2-stroke machine by Aprilia with the given name of RS250 Challenge. Reminds me the time of MotoGP era where we still can see 2-stroke bikes on the race with 125cc and 250cc class. It was a great time and the sound the 2-stroke machine is nice. This particular Aprilia RS250 share the same engine with the lovable Suzuki RGV250 VJ22 but tuned for higher power output and styling that is so Italian. This could be a bike that you can even park it in your living room and stare at it all day when you are not riding it.

Bridgestone introduces new tyre markings so the fans can know what type of the tyre the rider is using in MotoGP 2014

Extra-soft compound: Green
Soft compound: White
Medium compound: Black (no stripe)
Hard compound: Red
From the first race of the 2014 season, Bridgestone will employ a new colour marking system for its MotoGP™ tyres to make it easier for spectators to see which front and rear tyre options each rider is using at a given time.
The change in the tyre marking system has been devised in response to the Factory and Open-class machines having access to different rear slick options over a race weekend. The old marking system denoted the softer option tyre at each race with a white stripe, regardless of the compound specification of that tyre. The new system means that each of the four slick tyre compounds – Extra-soft, Soft, Medium and Hard – will have its own particular colour for the whole race season.
This change will make it easier for fans to distinguish between the Factory and Open-class tyre allocation, and also distinguish the different front and rear tyre combinations available to riders over a race weekend.
The colour scheme for the 2014 Bridgestone MotoGP slick tyres is as follows:
  • Extra-soft compound: Green
  • Soft compound: White
  • Medium compound: Black (no stripe)
  • Hard compound: Red
As only two options of wet tyre will be offered for each MotoGP round; wet tyres will still adopt the previous marking system with the plain, black tyre denoting the harder option, while the softer option will be marked with a white stripe.
Hiroshi Yamada – Manager, Bridgestone Motorsport Department
“The new tyre marking scheme is designed to make it easier for fans to see which tyre compound each rider is using on the front and rear of the bike. Before last year when the whole grid was on the same tyre compounds, our old marking system worked perfectly. Since the introduction of the CRT class, and now the grid being split between the Factory and Open-class machines, we’ve decided to change the marking system to suit. Last year, when our marking system used the white stripe to denote the softer option for each class, the audience needed to know if a rider was a Factory or CRT bike to know which compound was being used. Now, even if our audience doesn’t necessarily know the difference between a Factory and Open class bike, by matching distinct colours to each of our tyre compounds they will be able to tell the exact tyre choice of each rider.
 
“We must also consider that the growing popularity of MotoGP means more and more new fans are tuning in to watch races, and we feel that this new system will make it easier to understand the riders’ tyre choice and add an extra dimension to the MotoGP coverage.”
