Lowering front for 21" wheel ???'s

If this has been covered, please feel free to point me to that thread, and thanks in advance for any info shared.

Thinking about putting a 21" wheel on my 2004 FLTRI and was curious how much to lower the front to keep the bike at the same height. I'd love more clearance for aggressive corners, but at 5'9" I don't want to go any higher (and def do not want to go any lower either).

The stock wheel is a 16", so simple logic says I should lower the front 2.5 inches BUT that is not taking into account the height of the tire. Are the tires (21"x3.5") lower profile than the stock tire? If so, by how much??

What every inches you drop in the back do the same for the front and you should be fine.

The 21" wheel is about 2" in diameter larger than the stock 16. A 1" drop would make it level with the stock rear wheel.

2011 RGU with more money then sence in it.
Oh and its black because blacks faster.

Thanks. Just to be clear:

Even though the21" wheel is 5" bigger than stock, the tire is a lower profile, so the total is only about 4" bigger (or 2" if we're talking diameter)?

If I am not touching the back wheel or suspension, I only have to drop the front suspension 1" to keep it at the height it's at now (level)?

The sits 1" to 1.25" higher than it does stock. I am your height and am not a fan lowering the bike. Just my opinion. My advice is put the wheel on first and ride the bike. If you feel that lowering will benefit you (You will have reduced travel in the forks leading to a ride that is a bit rougher) lower it then. If you do both at the same time you have no way of knowing what has affected what. Just my .02.

I understand wanting to get everything done at once as well but I prefer to take my time and feel what kind of effect each change has made on the bike.

Hell I am 300# and run a 21" front with a wrap fender and -2 drop Progressive cartridges. All I can tell you is it is the best money I ever spent. My RG turns like a sport bike... I dive it in the corners and roll it off and it is a blast to ride...Rear is lowered 2 inches as well... I do recommend trying different set ups until you find what works best for you. Its all a matter of opinion and rider ability...

Man, I am totally stock, ride very aggressive, and scrape all the time. I love the lowered look, but would not want to lose any cornering ability.


For a 2004, is 21" the biggest you can bolt on with out raking?

For any year 2000- current 21" is the biggest without a raked tree and different front fender.

That's what I thought. Thanks.

I like the idea of doing one thing at a time, however, I know for sure that I do not want to go even a centimeter higher than I am right now (for looks AND for keeping both feet on the ground).

You can squeeze a 23" with a different fender but without a triple tree and the proper rake it has several issues. A, the wheel si quite heavy. B, there is not enough clearance between the crash bar and fender and lower triple tree and fender. C, if you want a good ride get a raked triple tree designed for a 23" wheel. Do it right the first time and avoid dented fenders and having to repaint and then dent it again.

We do make a bracket to raise the stock fender enough to allow it to work with a 23" wheel but it sits so close to the crash bar and lower tree that you basically have to make the forks as hard as a rock to keep them from coming in contact with each other.

I rode a bike like this and hated it. Rode with 23" triple trees and it rode great.
