Yamaha Motor India is to usethe 'DiASil' (die-casting Aluminum-Silicon) technology the Indian market, to be used in the new 150cc YZF-R15 bike, which will be launched later this year.

The YZF-R15 was unveiled at the Auto Expo in January here. "Developed in 2002 by Yamaha Motor Co, the DiASil technology uses an all-aluminum die-cast cylinder with 60 per cent better cooling performance and 30 per cent cheaper production cost than a conventional cylinder," it said.

YZF-15 will surely make a buzz in market when it will get launched.
Earlier I think Yamaha had some stupid taking care of Indian market.

No, it is simply for the 150cc segment and yes, in that segment it will create some fuzz but real can been seen only when it will get launched.

What they are trying to do is to cash upon the popularity of their higher counterpart ie. Yamaha YZR R1 .. you can see that its YZF-15 is clearly inspired from R1
