    With those BPF Showa, maybe you can put a zx or gsxr front end from the forks down.

    It's not hard to put a different front end on one of these bikes.

    The forks are 54mm bodies, but the steering stem is the same as an R1 -- I've seen exactly what you are proposing done. You could also get the Ohlins 54mm forks with traditional bottoms and then use any front wheel you wanted by machining spacers.

    I have always felt like the front brake was a liability vs. the traditional two-disc set up, but I've been able to get mine to where it's not something I think about anymore. The main "trick" is mounting the rotor with copper washers so the wheel itself becomes a heat-sink. The other "tricks" are common to even dual disc set-ups: removing the retaining clips for better airflow, using good fluid, etc.

    I've no doubt at a professional level the brake needs a lot of TLC. But at my skill level, a rotor lasts about 6 months, and they are less expensive to service compared to the dual-disc set-ups. A new rotor and fresh mounting hardware is under $200.

    Good grief Danny, you don't see me posting non-stop on cop forums how bad Oklahoma donuts are. We're still excited to see this bike released for production and can't wait to see what it's capable of in, say, Heavyweight Twins.

    I had no idea those things were very much "consumable." Do the 2-disc bikes need replacement like that? My wussy SV has never seen a rotor swap.

    At my skill level, the only 2-disc system I've ever had to service was one that the buttons wore out.

    The rotors on the EBR system lose their "bite" over time. Servicing them with some 100-grit helps (as is also the case with 2 disc systems), but yes, they wear out more quickly than 2 disc systems do. Rotors are definitely consumables on the EBR system when used in racing applications.

    If you are willing to pay a weight penalty, you can get 6mm rotors that last longer. I don't like them; they make the bike harder to turn.

    The EBR system is lighter than most dual-disc set-ups by 2-4 pounds. I'm not convinced, however, that once spinning at 60 mph they have less gyroscopic resistance to directional changes than do traditional designs. I'm not sure how to test it, though.

    Also worth considering: Your SV carries more cornerspeed, weighs less, and needs to slow less for each corner than my 1125r. So, your demands for braking are also less.

    Are you sure about the first two? Lots of people say the SV or "smaller" bikes can corner at higher speeds, but I don't see that physics support that. How much do you think my SV weighs? More than most 600cc race bikes. I guess your bike weighs a little more.
