2020 Kawasaki Z H2 Supercharged Streetfighter Product Development Update: Bolt-on Swingarm Extensions Installations Video with Additional Considerations Discussion.
Bolt-on swingarm extensions are a quick/easy/economical what to safely increase the wheelbase of most motorcycles so as to increase high-speed stability and decrease wheelies for quicker E.T.s at the drag strip – BONUS… stretched bikes look MUCH COOLER!
Now, before we hear from the “OMG…why-Why-WHY would you ruin the look and handling of such a fantastic machine?!” Gallery, please remember this video is not intended for you. We will address riding a 220+ RWHP sportbike with a 57” wheelbase soon enough.
For those interested in the benefits of a longer wheelbase, regardless of which make/model you ride, please watch on as Brock not only discusses the proper installation techniques in regard to bolt-on extensions, but he also outlines additional considerations to address while doing so. Having all of your “ducks in a row,” as they say can help alleviate frustration as well as additional downtime.
