    You can get the right size and ratio turbo and it prevents lightswitch style boost situations. The turbo has to be matched to the engine. Basically you want the turbo to build boost slowly before the peak torque of the engine, rather than all hitting at once at peak torque.

    For a turbo'd motorbike, normally the boost is kept low (5-7PSI) , and you can get a small turbo so it can generate boost throughout the rev range without taking a massive boost hit at a particular rpm.

    Superchargers would be better though for large motorbike engines, everything would definitely be linear with rpm there.

    120 whp would still be a nice change of pace.

    Yeah, a bunch of gearheads on a motorcycle forum talking about the intricacies of how a turbo works. Weird! Has anyone seen Rhianna's new video?

    However you'd only be able to get around 120 HP and added weight and complexity. So you'd be better off trading it up for a litre bike which would be more power and lighter anyway.

    Prices : (you could double this).
    - manifold and exhaust $1500
    - turbo $1000
    - Big injectors ~$500-700
    - ECU replacement with additional sensors and retuned by a good tuner ? $2500 ?

    If you tune them for a living and can make up your own manifolds, it may be worth it if you have lots of spare time and like doing lots of work.

    If you replace the pistons for more boost, you definitely should be buying a new bike at this point.
    Christ, where'd you pull those prices from?
    So far I have a gt2871 turbo, 220cc injectors for under $500.
    Piping will be 300.
    Tuning is 600.
    Map sensor is under 100

    As far as theory goes, the FZ6R is almost the perfect bike for a turbo. The original R6 engine that it is derived from was in the 120-135 HP range, so the basic Engine & Transmission should be able to handle the power reliably. Forced induction - either super or turbocharging - is exactly what the engine needs to overcome the reduced airflow created when Yamaha hobbled the engine with smaller throttle bodies, ports, and mild cam timing.

    As already stated, the easy and economical way to more power is to simply trade up. Even if the forced induction mod turns out perfectly, you still have a chassis with non-adjustable suspension that would probably be sketchy above 100HP.
    Now: 2015 FZ6R & 2008 WR250R
    Past: 2009 FZ6R & 2008 CBR1000RR
