18", 19" and 21" front tires for GZ250

[descargaelbano]

After doing exhaustive research into finding a 21 inch front wheel that would fit directly onto my bike without ANY modification turned into a dead end, but I have found that any of my older Suzuki GS/GT bikes with spokes up to 1000cc apparently will fit if you use your GZ rotor. The hub part numbers are different for the older larger bikes because they are drilled for rotors on both sides. The older bikes also have the same speedometer notches so they fit right on also.

If you are looking for a 19" for the front of your bike, use a front wheel from a GT550, GT380 or GS450 readily available on ebay. The GT250 comes in 18" which would have been great for me since I already had a brand new Sava MC7 3.50x18 tire laying around, but the 18 didn't have the large diameter I was looking for.

I ended up picking up a chrome Marshin rim 21x1.6 on ebay for $60 and getting the spokes(part#2000137) on sale at J&P Cycles for $32 and a Shinko 777 80/90-21 for $48. The correct chrome Radaelli rim was $137 so I opted for the Marshin rim, although new is a little lumpy at the sides. The tire was a bitch to put on!!! The hub holes will need to be drilled slightly larger and the spoke threads will need to be trimmed approximately 1/16".

Here's a pic of the 21 on the GZ. It still sits on the kickstand fine and you notice the top of the tire is at the same height as the fender so you can slide the fork tubes up through the top trees and use clip-ons above the top tree.

I hope any of this info helps, but just be sure to get measurements from sellers before buying any parts.
