Progressive Suspension

Progressive Suspension shocks and fork components are “exact fit” products. This means when you purchase their products they are tested and fitted for your specific bike. For shocks, this means the valving, as well as the spring rates, vary depending upon the motorcycle and payloads the bike will see. On the other hand, factory shocks that come stock on your bike, are more generic for obvious production reasons. No matter how fast your bike is, or how good it looks, none of that is important unless you are getting a comfortable and safe ride. Whether you have just purchased a new bike or upgrading a pre-owned bike, suspension should always be one of your first considerations when looking to improve your motorcycle.

With numerous choices in aftermarket suspension, Progressive Suspension makes it easy by offering a wide range of products with varying degrees of price and performance. Here is a a short summary of motorcycle suspension parts they offer.

  • As mentioned earlier, most series of shocks have many different designs depending upon the bike fitment. As an example, the 412 Series (as of the date of this article) consists of over 175 different models. Again, each of which are designed for a particular bike or bikes and predicted payloads. For bolt-on shocks, this is about as good as it gets without paying for a custom shock.

    If you are not sure which products to select based upon your motorcycle and riding needs, then speak to a qualified technician before making your purchase.
