Race Wheels is a front enough

[APP_Racing]

Looking to replace a stock wheel(s) (03 SV650) with some (hopefully) Marchessini's.  Because of the price and other items I need to do over the winter I was wondering?

If you were to only replace 1 wheel (assuming a front) is there any cons to this type of setup.  Or do they really need to be matched. 

Also, if you were to replace the rear; How important would it be to go to a 180 vs. 160.  My assumption would be that the 160 is sufficent and the reduced weight of the 160 would offset any traction gains of the 180.

Pros Front:  Sharper steering & quicker braking due to less rotating mass

Pros Rear:  Better acceleration, ability to fit a 180 tire.

There are SV guys who will smoke you with a 160 tire, and SV guys who say it made all the difference to switch to a 180.  If you don't already have a full-on 700 motor with cams & flatslides, then spend your money there instead.
If I had 2K to spend on my bike, I'd put it into the forks before I bought 1/2 a set of lightweight wheels.  A 25mm kit is a beautiful thing.

What he said...

First off, im still going to catch you from the amatuer grid no matter what  . j/k. But anyway, not sure which wheel will work better, i would assume the rear would be better due to the overall weight. Especially since unless you have really lightweight front rotors, they will be one of the primary gyroscopic forces on the bike. The thing about mag wheels are they arent necesarily immensly lighter, but they have something like 80 - 90 % of their weight in their hubs, making the outer rim extremely light and therefor fighting the good fight against one of our enemies, gyscoping wheels. My 5.5 rear marchesini with a tire mounted isnt a bunch lighter than my 4.5 sv wheel with tire. But seeing that you will be running it with a superbike motor, I would suggest going with a rear wheel and getting a 5.5. I way way prefered my 180, not for any huge reasons, but a whole bunch of little ones. there was similar tire wear from my 160 vs. 180, however when the tires went off I felt alot more confident on the 180. ohh yeah and its spelled Marchesini, its written on my rims you are welcome to come look

Curt Henderson or Ben Probst? Who gets the YPS torch? :)

Thanks, to all.  Including the English Teacher Ben Probst ;)
The bike as a 750 front end with Traxxion Cartridges?  Is that the same thing that everyone is mentioning about 25mm?

Motor is mildly tuned with some a 2mm piston.  No dyno work just yet so do not have any idea on power.

So for the next question?

Where do you get the best deal on a set of wheels? 

[Jack_Brock]

You guys need to leave stuff alone(i.e. leave it superstock), and focus on riding.  I left mine alone for the first 3 races of the year and everything was peachy.  Then I started experimenting with the internals on the front end and ended up on my head twice in consecutive weekends.  This does nothing for confidence or lap times.  Frankly, I was a little messed up after this, so I was glad to get out of MAM in one piece.

So for next year, I'm going back to what I had in the front end before, and I'm not touching it.  All of my effort all weekend will be on riding what I have, and hopefully nothing else.  I hope the rest of you give this some thought.  It would save you a bunch of money, I'd love to see you on the SS grid, and it might make you a better rider in the end.

Of course, you could build a full blown superbike, and go blow away all the amatuers, that would be cool!

Anthony has a SS bike too... 

Anthony-you have AK-20's which are as close to 25mm ohlins as you can get.  Good stuff!  Really wheels are about the only thing you don't have so I would go for it.  I think the mag front on the SV I rode made a pretty big difference!

The superbike smokin amatuers joke was aimed at Ben if there was any doubt.

From Bens comment, it sounds like Anthony may be moving up, so good for him if this is the case.

Yep, I ran a SS bike with U4, exhaust, and a rear shock all year long in SB.  Only time I really wished it was built more was at Daytona on the Banking.

Don't forget you had the 12 lb. rider mod also...  ;)
