Bergfelt's Bumpers

The Most Popular Aftermarket Loop Style Race Kart Bumpers in the USA !

Bergfelt's Bumper Jr Max kart
Cage Kart Bumper
Bergfelt Racing Enterprises is pleased to offer our Custom Bumpers for kart racers. We have been supplying bumpers since 2001. Most of the bumpers pictured on this page are the loop style that are meant to minimize the chance of other karts climbing over in the event of contact with the rear tires. We can also fabricate more conventional bumpers.

 

Are Bergfelt's Bumpers legal for my racing association?

We are often asked if our bumpers are legal for WKA, IKF, as well as other associations. They are recommended by clubs all over the USA. Bergfelt's Bumpers pre-date those rules. When WKA first introduced full coverage bumpers for sprint karts in the junior enduro classes, our phone really started to ring. During the first season that Rotax Max implemented a full coverage bumper for their junior classes, ours were the bumpers that they recommended and the rule that they developed after that describes our standard bumper to a "t". Later on, the enduro kart racing club that races at Summit Point closely studied our bumpers when they were developing their full coverage bumper rule as well. It is our understanding that the final version of the WKA rule developed from what that club learned from our bumpers. Clubs all over the USA recommend our bumpers. We have made many, many for WKA, IKF, Rotax Max, Unlimited All-Stars, and other clubs and associations for sprint, enduro and speedway kart racing. Please note that in 2009 Rotax Max started requiring the use of the bulky plastic box type bumpers. It's too bad that they do not allow their racers the advantages of steel tube bumpers.

 

 

Bergfelt's Bumpers are made from quality 3/4" od, mild steel tubing and are MIG welded. We use mild steel because the bumper should bend in a hard collision. As the bumper bends, it absorbs the shock protecting the driver and the chassis. The bumpers are supplied unfinished, ie. they are not chrome plated or painted. We leave that up to the customer.

 

This is our original prototype bumper that was made for a CRG Heron Oval chassis. It was finished with Rustoleum spray paint.

 

Prototype bumper

 

flex option Early in 2010 a road racer on the West Coast asked us to fabricate a bumper that attached the top of the extended end loop with a tie rod bearing and the bottom with a piece of hose, so we did. During that season another racer was close behind the racer with our bumper when the kart lost power and slowed abruptly. The driver of the following kart reacted quickly but still managed to clip the rear corner of the slowing kart pretty hard. After the race he found the driver of that kart to see how he was and was surprised to find absolutely no damage to the kart or bumper from the impact. That Bergfelt Bumper had done it's job and was ready immediately to do it again. When it was time for the second racer to get a new bumper you know who he called. The bumper in the pictures above is the restyled version of the bumper described in the story. It was designed to look like our original bumpers but still have the flexible end function. To get one for yourself just ask for the FLEX OPTION. The flex end option only adds $26 to the price of the bumper and that can really pay off when you don't have to replace bumpers with bent up ends. Please note that this option is not IKF legal.
 

 

Standard Style Bumpers

The karts above were spotted at the 2005 R-Max Nationals. These karts were competing in the JR Max division that requires an extended bumper. Our bumpers fit the bill perfectly. They fit the karts perfectly too! Both of these karts are fitted with what we call the original "symmetrical" style because the loops stick out evenly on both sides.

 

 

Off-Set Bumpers for Oval Karts

 

offset bumper
This is an offset bumper for Mongoose dirt oval chassis. We call this an original style asymmetrical bumper because the loops stick out more on one side than the other. It has the standard ends.

 

Jamaican Center Style Bumpers

 

In November of 2005 we had a request to make a bumper by a kart racer in Jamaica. That racer requested a bumper that was just a little different but very strong in the center. Our new Jamaican center style bumper is the result. This is our most sturdy style bumper. It is an especially good choice if you want to tighten the kart up and the installer is using the rubber insert mounting method. To keep the chassis free we recommend the use of no-bind pins with this bumper style.

West Coast Ends Style Bumpers

The West Coast Optional ends are available with either standard or Jamaican style middle sections.

Add $15 to the total bumper price for the West Coast style ends.

Please note; We do not provide chrome plating service. The customer arranged for the plating on his own.

 

Margay / Trackmagic Style Bumpers

 

Margay and Trackmagic Karts have a unique mounting method. This picture illustrates the bumper that we make for those applications. Add $15 to the calculated price for this style. Our most recent model of this bumper does not have the bottom horizontal tube and looks just like the Jamaican Center. This bumper is also offered with a standard drop loop type center.

Unimited All-Stars Wedge Body Style Bumpers

 

Wedge Body Bumper

 

New for 2010 is the UAS Wedge body style bumper. The bumper pictured features the West Coast double bend ends but it is also available with the standard single bend ends. This bumper was designed to tie onto the sideboards of the wedge bodies of Unlimited All-Stars karts. Go to http://www.unlimitedallstars.org to learn more about this exciting division of karting. This bumper is designed to maximize the downforce created by the wedge body. It must be installed using our exclusive no-bind pins with extension bushings.

This picture shows in detail the no-bind pin, extension bushing and frame tube adaptor bushing used on the UAS Wedge Body bumper. All that needs to be done is to insert the pin and bushing assembly into the end of the frame rails, cross drill with a 1/4" drill and install a high grade bolt with a lock nut. This mounting method is more secure than the standard rubber inserts and allows more chassis flexibility than any other other mounting method that we know of.

When ordering this bumper we need to know the distance from the center of the left frame rail to the inside of the side board, the distance from the center of the right frame tube to the inside of the right side board, the center to center distance of the frame rails and the inside diameter of the frame rail tubes. The entire kit with the West Coast Ends is $100 and with the standard ends (not-pictured) $90.

Canadian Style Bumpers

 

Canadian Bumper

 

During the summer of 2011 a Canadian racer, who did not want to use the plastic box type bumpers, sent us a copy of the Canadian bumper regulations. We were happy to fabricate a bumper that met those specifications. Please note that the rules mandate the solid lower horizontal tube. These bumpers are $77 up to 36" long and add .75 for each additional inch of length.

 

Cage / Champ Kart Rear Bumpers

 

Some tracks and clubs require cage type race karts to now have a squared off rear bumper rather than the older pointed sprint car style bumpers. We make them. Call or e-mail for ordering details and pricing. The bumper pictured here was $75.00

Vintage Kart Bumpers

These pictures were taken at the 2005 Vintage Kart Nationals at Fremont, Ohio.

At one time we had a special order for a reproduction of an aftermarket bumper that was produced for the Rupp Dart Kart and A-bone kart. The original was made from 5/8 tubing. Our first reproduction was made from 3/4 tubing but we now can produce them from 5/8" tubing. Producing this bumper required the fabrication of a set of patterns and jigs. We are offering these bumpers for $89 each, and $160 for a set of front and rear bumpers. They are considerally more work to make than the loop bumpers shown above. We do not provide chrome plating. The customers had that done on their own.

We are willing to make reproductions of other vintage bumpers. Please contact us for details.

 

 

Exhaust Pipe Mounting

 

Exhaust Bracket
Click on picture for larger image of our integral exhaust pipe bracket. The bracket can be positioned along any horizontal tube on the bumper but must be installed when the bumper is being fabricated. This option is $20 extra.

 

Custom Nerf Bars

 

We made this set of custom nerf bars for a very successful Unlimited All-Stars racer to his specifications. We can do that for other racers as well.

We make "standard' style nerf bars too.

Nerf bars are more difficult to get an accurate fit so we prefer to have the old bars or the kart itself to make sure that the fit is correct. Of course pricing depends upon the complexity of the design and the amount of material that is required.

Call or e-mail for details.

Bumper Mounting

There are two basic methods of mounting rear kart bumpers;

 


1. A special rubber bushing is inserted into the frame rails and a bolt is inserted through an eye on the bumper into the threads in the special bushing. The bumper pictured below was made for that type of application. This is the most common method used for sprint karts but is also employed by some oval chassis. We highly recommend that the mounting bolt is safety wired to the kart chassis.

2. The second method requires that there are tubes attached to the bumper that insert into the ends of the frame rails. The frame rail and the bumper insert are cross drilled and a bolt is inserted through them to secure the bumper. This method is often used in an attempt to keep the bumper from "binding up" the chassis or preventing it from flexing freely, but since the bolt is tight, and prevents twist, some binding of the chassis still exists. The bumpers that we make for this type of application utilize our unique no-bind technique pictured below.We recommend putting some grease on the pin where it fits through the bumper eye to insure that rust and corrosion will not form in the joint limiting flexibility.

Bumper Hardware

 

Bumper Hardware

Adaptor Plug / Frame to Bumper/Machined Aluminum

Specify if for: 28mm / 1 1/8", 30mm / 1 3/16", 32mm / 1 1/4" outside diameter frame tubes.

End Plugs/Machined Aluminum

Bumper Bolts M10

Our B.R.E. Exclusive No-bind Bushing

These are inserted between the adaptor plug and end plug so that the bumper bolt can be tightened but the bumper is still allowed to float.

The bushing can be easily removed if it is desirable to have the bumper tighter to fine-tune handling.

Call for current pricing of bumper hardware. Since we purchase these items and slightly modify them to fit our bumpers we have little control over the pricing.
