I for one am glad the core of the busa remained na and not turbo or charged... I wouldn't have bought it.
Apart from motorways locally there aren't enough roads to use that extra power and to retain the low rpm grunt and instant response would have been near impossible especially for EU5. Those who feel 500hp is what they need then keep the Gen1 or 2 as you'll never use the new electronics and what percentage of totally busa sales do you represent... That's how Suzuki will have looked at it when making the Gen3... Even if the turbo group was 30 to 40% they wouldn't risk loosing the other 60% on a bike that few wanted or could control.
I'll stick to the Gen 3 on the roads that just happen to cater for the fastest roads races in the world yet have only a few straights.... The new busa has added some nice cornering talents and toys.
Is it safe... Yes... Is it boring for having rider aids.. No... We all set our own bikes up to do what we want and I feel that most owners will find the Gen3 is just what they want.... I do understand the pricing issue many have and that's a personal choice that each buyer has to accept.
It's not the ultimate performance bike but its got performance most bikes cannot live with and still retains the overtaking punch that makes fast riding enjoyable without bouncing off a rev limiter.
