Just picked up an 06 street bob and plan on purchasing the Burly Slammer kit. Question I have is if I will run into any issues running a 21x3.5 wheel in the front and an 18X5.5 rear in the wheel. Tires will be a 120/70 and 200 in the rear. Is there anything I need to be aware of and is will I be able to adjust the height either in the front or rear with the slammer kit?

 

No problem up front.

Rear will need slight mods to inner fender brackets and likely removal of stock-style rear turns signals, taillights, and associated wiring.

 

thanks for the quick resposne...will remove the rear turn signals and will have vertical license plate mount with tailight, so should be good then...how about riding 2up, any issues there? I won't be riding 2up often but just curious?

 

Although I have no experience with riding 2-up on my bike, there should be no problems with that either.

 

Are your re-lacing your hub (assuming you have laced wheel) to a 3.5 hoop or did you find a Mid-glide wheel?

 

will re-lace to 3.5 hoop

 

Will I have to find another hub for my streetbob if I want to run a 21x3.5 80 spoke DNA wheel for the front and 18x5.5 rear wheel or can I use the stock hub?

 

Go out and count the # of spokes on your stock hub...What do you think?

 

just found the answer as well...which hub can I use or where can I source a hub that will work on my bike?

 

5.5" is kinda narrow for a 200. It's doable, I've got one, but please ensure the chosen tire is rated for a rim of that width.

As for a hub source...
