Körde lite aktivt med min -96 blade, och jo, i VISSA kurvor kändes det som den verkligen FÖLL in i kurvorna.
Folk säger: Det är skottkärrshjulet. (Den har ett 16" fram) Sätt på ett 17 från en 600, blackbird eller en VFR.
Så hittade jag detta Engelska test av just detta fenomen. Nån som har några kommentarer av er övriga bladerunners?
The CBR 900 RR has been labeled as having a nervous front end due to the steep steering geometry and it's 16" front wheel. Critics have called for the bike to be issued with a 17" front wheel to increase the front's stability over bumpy corners. In reality, the 16" wheel is more an issue of not having a wide variety of rubber available. With proper front end setup the CBR's leading end is just fine for sport road riding. However, for serious racing applications the 17" front is a must.
The following is a test performed by FARROKH JAHANDARI and Slipstream Racing. Draw your own conclusions from the data. Great job guys!
>Here is what we did. We tested a stock 1994 (only mod was a steering damper) with two sets of different tires and then compared it to my relatively highly modified 1995 (17-inch F-3 front wheel, BT56 tires, steering damper, RaceTech Gold valves forks, stiffer RT fork springs and 7-Wt oil.)
Test 1: 1994 bike was fitted with both a BT50 front and rear. "Myth" was there big time; steering performance was crap with scary oversteer and over leans into a turn scenario.
Test 2: 1994 bike with MEZ-1 race front and MEZ-1 rear. Awesome, felt like a totally new front end on a new bike. The "myth" was completely gone. Felt solid, turned well and without any of the oversteer or the lean scenario. Remember all we did was change the rubbers.
Test 3: We compared the 1994 bike setup in Test 2 with my 1995. The two bikes felt very similar, hardly justifying any of the significant fork, and wheel changes totaling well over $1,000! It became very obvious that very few differences are caused by the reworked fork work and the 17-inch wheel on most street riding scenarios.
Test 4: We changed the tires on my 1995 bike to MEZ-1 Race fronts and MEZ-1 rears. Then we pitted both the 94 and 95 with identical tires against each other to see the differences. Both riders regularly switched bikes and exchanged comments. We both felt that the MEZ-1 made the 95 bike feel a little bit better in some turns; however, overall differences were minor. The only difference between the BT56 and MEZ-1 on the 95 bike was that it stoppies like a mother fu**er! Otherwise for most road conditions and advanced street riding the changes between the BT56 and MEZ-1 are moderate.
Conclusions: Test 1 clearly indicated that the Bridgestone BT50 is totally worthless shit. IT seems to solely cause "The Phenomenon", as shown in Tests 2 and 3. Here is the *real* kicker though. There was hardly ANY difference between the bikes in Test 2 and 3 in almost all typical advanced road riding scenarios. Want to do hard leans and flick on the street? Go with a MEZ-1 Race front MEZ-1/2 rear *or* the BT56 on both. Save all the money for fork and wheels and do better things with it. As we seem to read again and again, the 900-RR FireBlade IS very sensitive to front tires. Get the best tire you can afford; it will make a *huge* difference. Also front tire wear is critical, replace frequently! The BT50 seems to wear unevenly and poorly further screwing up the front end.
Moral of the story is this. Get rid of your BT50 ASAP. Then either get a BT56 or a MEZ-1 setup based on your own feelings and or availability. If you want to Stoppie then go to the MEZ-1 RACE front and regular MEZ-1 or MEZ-2 on your rear. This solution is very easy, it is relatively cheap, and it *really* works. Also remember that when you get a 17-inch wheel for the front you are *adding* weight. Which is a no-no for wheelies and general weight issues on a ultra high performance bike.. etc.!
