[xxdevilzeroxx]

i rode my friends 195-65-17 at the track, i currently use 200-55-17 on my bike.. i like the quick flick on the 65" what do you guys think about lowering the front 5mm?

Pros:
Cons:

? I'm confused... Those are rear sizes and your asking about front tire?

I think you should get rid of the 200 rear tire. IMHO that's great for looks but your agility may suffer a bit.

These days some racers are actually raising both ends of the bike for greater handling, hence the availability of fork extenders and rear shock links for increased ride height and CG.

I am not asking about front tire sizes.

so you are saying Aprilia and Duck are putting 200s on the new 1000s for looks? ive tracked with both size tires and i can honestly say corner grip with 200s feel better for me.

At full lean the 200 will give you more surface area on the pavement for a bit more grip.

lowering the front a bit will help with initial turn in, and 5mm shouldn't be a problem at all.

Play with it, see what you like and what feels good to you. My 636 track bike ive got the forks down in the triples about 10mm. you can also raise the rear a bit to do the same thing.

Not all manufacturers have the same frame geometry. Wheelbase, swingarm pivot height/swingarm angle, F/R ride height, rake/trail (front), etc., it all contributes. When you installed that 200-size rear it probably did raise the rear ride height a tad, *can* improved turn in. However, it's been my experience that you can potentially suffer from mid-corner to exit...you can run a bit wide. I know this sounds counter-intuitive but raising the front of the bike (lowering the forks in the clamps) can possibly restore your neutral handling. Hence the availability if those fork tube extenders I previously mentioned. GP Suspension quotes thus:

With the ever-growing demand of larger diameter rear tires from the major tire manufactures, there has been a need for additional trail needed to be put back in the chassis. With the new fork caps for the 2006 GSXR 600/750 you are allowed to lift the motorcycle and additional 15mm for increased trail and also gaining swing arm angle.

These are a popular mod for the GSXR's; you can use them on the CBR but, AFAIK, only if you have an Ohlins fork cartridge kit installed.

i ran a 125/80/17 front with both the 195 and 200 rear. the 195 does grip a bit better in the meat portion of the tire (getting on the gas after picking up off the edge) but the 200 is so close (and cheaper by $70 or so) that it really never made a difference to me. the 195 and the 200 are very close to the same profile so saying that you can tell a difference at tip in is a bit strange.

i wouldnt lower the front. just bet a bit bigger front tire.

in the end, if you want the same numbers as what you are used to, you need to measure your bike with what tires are on it. switch tires and re measure. adjust your ride height back to where it was originally.

The stock suspension setup of the 2012 has the caps pretty much already flush with the upper clamps. If there is a way to lower the tubes in the clamps a few mm's it's possible that you can get your bike with that 200-rear to handle pretty closely as it did with the stock 190.
