I have a 2003 a LEONARDO that I recently purchased used. 2000 miles on her. The front wheel had a flat spot that caused some front hop. I had my local dealer order a new wheel. The hop is gone but there is an ever so slight head shake at about 45 mph. I am running Metzlers which are also new. Has anyone had a similar issue. Is this acceptable for these aluminum spoked wheels? Help appreciated.

Re: Front Wheel Problem
Sorry you're having problems with your new bike give it a bit of time and you'll work through the issues. Be patient.
First thing you should do is NOT trust the Aprilia 'experts' in GA. Your bike should not shake at 45 MPH. It is not within 'normal limits'. I routinely run up to 95MPH and she is smooth stable and confidence inspiring. Quite a few things (or a combination of factors) could be causing the wobble. The first thing I would recomend is that you find another shop that KNOWS exactly how to true a spoked wheel. Start with a good MX shop as they see simular wheels all the time. See what happens after they work with it.
There have been a number of people that report wobble on worn Metzlers but I don't recall new ones being an issue. It is possible (however unlikely) that you have a bad tire that is adding difficulty to the diagnosis.
What type of screen is on the bike and has it been modified. Do a search, a few people have reported low frequency harmonics or wobble with a certain aftermarket windscreen. Right now I can't remember which.
Do you have any handguards on the bike (BMW or Aprilia aftermarket)?
Are the bar end weights in place and OEM?
Have you assured that you don't have a slightly warped disk or breaking issue? When breaking does the bike break smooth, straight, and strong?
With a little effort I'm sure you'll figure out what's going on and you'll fall in love with the Capo. It has so much more 'soul' than the others...

hi, is this a woble, or a shake from the handlebars, when you let go of them, or while you are holding them, had new tyres or the wheels been removed recently, check front wheel spindle is tight 100nm 36 psi in front tyre, also check with the wheel of the ground that it spins freely, brake binde will cause this, has the rear wheel been removed and not tightened up correctly, has the spacer inside the rear sprocket housing been omited, remove wheel and check it in place, this will be evident if the rear wheel spindle continues to turn even when fully tight, check tyre pressure 36psi and tighten rear wheel to 100 nm also.
lastly a tyre which has been resting on the ground in the same place for a long period of time will also cause shakeing as the tyre carcus becomes distorted not visible to the eye, and only when you change the tyre do you experience the benefit, can also occure with a new tyre of low grade. paul
The scraping noise could be a brake pad rubbing on a rotor, most likely caused by not getting the axle set in the right spot after replacing the wheel bearings, (assuming everything else was done correctly). Start by supporting bike with front wheel off the ground. Loosen the front axle nut. Loosen the clamp on the bottom of the right side lower leg. Insert a 7/16" drill bit or steel rod or drill bit, (whatever will fit through the hole without too much slop). Tighten axle nut to 50 to 55 ft lbs. Tighten clamp nuts. Spin the wheel and operate the hand brake a few times. Wheel should now be centered with the brake rotors running in the center of the brake pads. If not, you may have mixed up the spacers.
provided the wheel and spacers were reinstalled correctly, you can loosen 3 of the 4 the tripple clamp pinch bolts and push the wheel against a wall until straight and retighten, the forks may have had a slight twist and the wheel was holding it straight, when the wheel was reinstalled the axle would pull them back to where they should be
Yeah, I'd say your front wheel is out of balance, might have thrown a wheel weight. Or somebody put some flat repair in there and it gobbed up in one spot. Get the wheel balanced, high speed, and if it still wobbles, get a steering damper on there. I had one om my monster when I bought it , but didn't really need it, so I took it off,. Hope this helps.
firstly are you running the manufacturers recomended tyre presures has the correct weight fork oil been used when they where rebuilt if the rear suspension has been set up for two up work & your doing mostly solo it will be to hard try a softer setting to much oil in the front forks will also make for a stiffer ride.more oil in one fork than the other may also contribute to the knobby tyre feel these are alll relatively easy checks to make. start with tyre pressures & go from there it may also pay you to slacken of the pinch bolts on the tripple clamps & allow the forks to center themselves this will need to be done with the machine on a lift with the front wheel off the ground position the front wheel in a straight ahead position with your knees either side holding the wheel firmly between your knees give the bars a tweek left & right allow the bars to center resecure the pinch bolts the other thing you might want to check are the rims for flat spots or buckles
Tread pattern can affect road noise considerably. Did you select a type designed for dirt? It would be a sort of rough buzz. Check for correct air pressure. An incorrect tire mounting usually causes a 'lumpy' ride and could be very dangerous at speed. Raise the front end till the wheel is clear and spin the tire. An improper mounting will show as an uneven tire pattern as the wheel turns.
but I mention Aprilia and they run for the hills. Seems like most people only want to work on Hondas and Harley's.
Does anyone think that this is a project that I should try myself?
Or is there anyone out there that knows of someone that could do a perfect job?I just got through dealing with the same problem. I even got a new wheel and it wasnt' true. The dealer couldn't true it because the wheel is too rigid. I found one of the best businesses I have ever come across during my search to get the wheel fixed. The company is Woody's Wheel Works in Colorado. I shipped them my wheel they trued it the day I got it and shipped it back out the next day. They are a great bunch of guys. The site is www.woodyswheelworks.com.
I can eard a metallic noise from the front wheel. Since 2 weeks I'm looking to find where he can come from and now I think I've found and I'm a little bit frightened.
This noise is comming from the front break disk they are moving in the screw place. See the picture
Have you ever see this problem ? Is it Normal ?,I think it's normal mate. Semi floating or floating discs are fitted so they do move. Someone more knowledgeable will be along soon I'm sure to confirm or correct me!,,,
