Well, CRAP! The video was just removed from YouTube and from the VISORDOWN website by the User....
I emailed them to put it back up, already.
I did get to watch it and they gave a slight edge to the RC390 as being the more aggressive Sport Bike. The YZF-R3 was just named Motorcycle of the Year in India today, though. And the RC390 is MADE in India.
Some (what I thought were) fairly unbiased reviews. The CBR300 is the weakest of the 300 class offerings, IMO, but the other three are all good entry level bikes - tweaked a bit and they're great entry level bikes. It'll be interesting to see what comes in the next couple of years as the class is becoming popular for both street and track.
It's pretty much impossible to buy the KTMRC390 for anywhere sticker price in the USA. A more average price would be around $6,500 which is way more expensive than the R3 which has real availability and a real dealer network.
