As Yamaha and Honda battle it out on track, and in the standings, Mick Doohan believes MotoGP is going through a "golden era" of fierce racing.
Honda's Marc Marquez won back-to-back titles in 2013 and 2014 but this season has been overhauled by the Yamaha pairing.
Heading into MotoGP's triple-header Valentino Rossi is leading the standings on 263 points while Jorge Lorenzo is 14 behind. Marquez is also mathematically still in the running as the defending Champ sits on 184 points.
All three have won races this season while Dani Pedrosa and the factory Ducati riders of Andrea Dovizioso and Andrea Iannone have also been battling at the front.
"I think at any given time in the sport there's normally only one or two guys that are strong enough to win a championship. There are always guys capable of winning races but normally it comes down to one or two guys," Doohan told Drive.com.au.
"There are a couple of guys in there at the moment who are capable of winning championships, and throughout the history of the sport there have only been a few eras like that. So you'd certainly have to say it is one of the better times for MotoGP.
"And I think the racing this year and the way the championship is coming down to the wire, it is showing itself to be certainly a golden era."
Pressed as to whom he believes he will this year's title, the MotoGP legend said: "It's just too close to call.
"Lorenzo is very quick and Rossi is very experienced. To be honest, you'd just be picking a name out of a hat. I think it would be great if Rossi won another title, due to the fact it would be great for the sport.
"And Lorenzo, he's been knocking at the door a few years now, he's already got two world titles, so for him to miss another one by a couple of points would be very sad to see. So it would be good to see him wrap up another championship.
"But honestly, it's just too close to call."
