Rear wheel doesn't spin freely

[creed]

First of all, great forum with great information shared.

I've a C650GT with 12,000 miles on it, and just went through the 12,000 miles services. I didn't realize till last week when I put my bike on a center stand and had a good wash, and while I'm spinning the rear wheel, felt there were friction like the brake pad was holding back the wheel from spinning freely.

I'm really not well versed in technical and all the while been sending my bikes back to the dealer, kick stand is up so it should not be the parking brake, and I've tried loosen the nut to make sure the parking brake is not the cause of the wheel not spinning freely.

What's the cause of this if anyone can shed some light, and should the wheel spins freely?

Appreciate guidance in any form

Cheers

At the 12k service were brakes bled or pads changed? Try riding for a short distance, use only front brake, if rear disc is very warm or hot may be dragging.

Yes, your pads could be sticking. The parking brake pads can stay sticking even if you loosen the nut, it might need lubrication or exercise of the parts. Taking it apart for cleaning or lubrication would help.The rear brake caliper might also be sticking (could be both) and the easiest thing to do is go for a ride, brake very hard, then release the brake and wiggle the bike side to side while moving. There is always some play in the bearings allowing the disc to push the pistons back into the caliper bodies. Do this several times and
it should help free the pistons. Babying disc brakes will almost surly cause sticky pistons, and your pads might last a little longer, but, repairing the stuck pistons will be way more expensive.Brake hard every day.
When I change my pads I exercise the pistons by moving them in and out several times to get the corrosion broken up. If you can't go for a ride to free your pistons, hit the caliper back and forth with a rubber hammer or a ball peen hammer cushioned with a piece of wood. A pry bar will work too.

It is a c.v.t., I think that sensation is normal, could be wrong but mine felt the same way. Paul

The CVT will create a little drag, but , not to the extent dragging brakes will.

The rear wheel can't spin freely, it's always linked to the drive chain which is connected to the driven pulley. There will be a good bit of drag when hand turning the rear wheel.

Ah, just reporting back I've done some hard braking and find when i spin the wheel, although its not spinning freely (with dragging as other points out), but indeed i felt better, as in the past when i spin it there is some accompanying light screeching sound which is now gone
