• KEEP IN MIND
• 1. You will need to remove stock rear fender to make room for the new large wheel. You will need to relocate the License plate. We do sell billet license plate relocaters with L.E.D. tag light.
• 2. Due to the width of the swingarm you will need to modify or replace the exhaust[and or exhaust mid-pipe to make clearance for the wider swingarm. We do sell 4-2-1 Dump systems that exit under the right side driver footpeg. We like to use this style on our builds but they have no cannister and are loud. We like the attention.
• 3. Whenever stretching a swingarm we like to add a heavy duty shock spring or custom built aftermarket shock to compensate for the added leverage of the longer swingarm.
• 4. Due to the rear wheel being so large (18" in diameter rather than 17") the tire will be closer and may come in contact with aftermarket undertails or tail section under tray if bike is set up to low.
• 5. All the rear tires of this size are developed for Harley's so they are a harder compound and will not get as much traction as your average street tire. Due to this reason we do not reccomend wide tire kits if you plan to race competitively or are very interested in strip times. This does make for some very fun 2-3 gear black strip burn outs we love so much. Ohh Yeah the tire lasts FOREVER too!!
