No performance bike has no excaleration and does not even lift front wheel

Have you made any adjustments to your chain lately ? is the tire pressure up to the right amount ? are any of your disk brake rotors getting hot even though you are not using them ? or drum brakes if your bike has them ? if the bike is on the centre stand or raised up of the ground can you spin the rear wheel and will move freely this also applies to the front wheel if it is also lifted off the ground can it spin freely ?doing this will answer your question

Either the wheel is not centered in the frame, It's the wrong diameter/width wheel, or the derailleur is crooked (or did you mean the chainwheels/sprockets?). Need clear picture or find in-person help - knowledgeable friend, bike co-op or bike shop.

lift the front of the bike and see if the wheel turns freely. if there is even the slightest catch in the wheel, it is most likely the wheel bearing going out...which you don't want at speed. it can also be brake pads singing against a smooth rotor. you can try taking rough sandpaper and lay it upright on a smooth surface. while wearing gloves the whole time, take off the front brake pads an rub the surfaces on the sandpaper. reinstall them and see if the noise quits. if so. you need a complete brake service on the front. if not, you should look into the wheel bearing further.

very easy to lower the bike. go to ebay and buy lowering link. you will need a bike stand too... lift rear and front wheels and jack the middle of the bike. find a hard part. remove the fairings. remove the stock bone and replace with the lowering link. you are all set.

Unhinge the Vbrake at the front, by ushing the arms together and sliding the silver metal pipe out of it's holder. The brkes should release their tension. Undo the front bolt going through the center of the wheel with two spanners.

Don't use one spanner as it turns the opposite side and you'll be there all day.

Lift the bike up and pull the front wheel out away from the forks.

Vote for me if you think this helps you. Thanks :)

If you mean when you are riding you need to lean back over the back of the seat as you pull up to get the front wheel off the ground

To remove the front tire, you'll need something to lift the bike with like a frame jack. Position the jack under the bike and lift it slighty but not completely off the ground. Make sure the bike is stable and will not fall.

Lift the bike until the weight is off the front wheel but the wheel is not off of the ground. Loosen and remove the axle nut and loosen the two bolts on the bottom of the fork slider on one side. Slide the axle out of the wheel.

Now, carefully continue to lift the bike until you can get the wheel out from under the front fender. Make sure that you mark or can remember where any spacers go and in what direction they face on the axle.

Drain the fron end fork and replace it using a recommended approch. Even levels and not air bound or a suchion bound may cause a stiff fromt end and not flexible enough that can not be noticed standing still and pushing down on the front end, This can cause a wobble that is like a loose wheel

First, you need a way to safely lift the bike off the ground so that there is no chance of it falling over. Lift the bike so that the wheel you're working on is just barely on the ground with no weight on it.

Let's take the front wheel first. Before you take anything off, look at the axle, spacers, speedo gear (if there is one) and everything else closely and remember how it looks. Next, take the nut of the end of the axle. Loosen the nuts on the clamp on the other side. Start sliding the axle out. As the axle comes out, take the spacers and either label them or lay them out so you can remember in which direction and order that they go back in. If your bike has a speedo drive on the front wheel, notice that the drive tang sits in a small slot on the wheel. When you go to put the wheel back on, do everything in reverse. Tighten the nut to 50 ft. lbs. and then tighten the two nuts of the clamp on the other side to 20 ft. lbs.

Rear wheel. Almost same as front wheel except you'll probably have to loosen the belt just a bit prior to sliding the axle out. Reinstall in the opposite order. Adjust tension on rear belt and align rear wheel straight in the swingarm. Tighten the rear axle nut to 50 ft. lbs.

When installing either wheel, you may have to spead the brake pads in order to get the disc started back up between them.

Double check all nuts, bolts, and test brakes on both wheels before riding. Failure to proper perform these procedures can result in serious injury or death. Don't hurt yourself because you forgot to tighten a nut.

Lift the front wheel, use jack or put something under the exhaust. Loosen the front wheel nut and pull out the bolt. Pull out the speedometer cap. Pull out the wheel. Now you got your front wheel off your bike. The rear wheel is harder to handle. You can bring the wheel to bike workshop or you can do it yourself provided that you got all the tools.
