The secret for Sportster Hooligan racers

Starting at $545

Do not buy this kit unless your steering head has these dimensions:

  • Steering head OD 2.90” (2 ¼")
  • ID of bearing race 1.932 (2” +/-)
  • ID of internal head 1.785”
  • Head length 7 1/8”

See the installation guide. Some late-model pre-rubber frames had narrower heads. Kit does not fit rubber frames.

Simply put my steering head insert kit moves the front
wheel and fork rearward 3 degrees for faster, easier,
more controlled cornering

The Sportster Racing QuikTurn 27°© is a product for those who race Sportsters on dirt tracks. It does not benefit road riders other than aesthetics.

The current rage of Hooligan racing (big twins on short tracks) is the reason this product was undertaken at considerable cost. Sportsters are big heavy motorcycles with a long 30° fork angle designed for stable road riding. Any attempt to put a stock Sportster on a short track will yield slow, awkward and difficult handling (all wrapped in the word ‘slow’).

27 deg steering kit 2Now let’s get into the nut. I will not bore you with minutia of rake, trail and offset geometry. A Sportster 30° fork angle stabilizes the front-end and keeps your motorcycle traveling the road in a straight line. Racing a stock Sportster exhibits heavy and sluggish handling because the weight of the chassis is attempting to self-straighten the fork in corners.

A steeper fork angle (27°) allows the motorcycle to "fall" into turns (race corners) for quick and easier turns. A bike with a steeper fork handles bumps and ruts well but forfeits some straight line stability but also produces a lighter handling feel when turning. This is good for racing. 27° is a happy medium between 30° road forks and serious dirt track forks with 25° and 26° fork angles.

Okay, your Sportster can be made to turn faster and easier with my steering kit without greatly effecting straight line stability. I would be cautious about extreme high speeds with an altered front end. I have had high speed wobbles with 25° fork angles but I’m guessing this won’t be a problem with my in-between kit angle. [Note my word “guessing.”]

Note: This kit will not fit frame heads with an I.D. noticeably less than 1.74”. These frames started appearing in 1997. Will not fit rubber frames after 2003 with narrow I.D. necks.

Kit is made for sliding

27 deg steering kit artNow if you have prior dirt track experience and have mastered “sliding” into corners, my kit will be a happy addition to your ability to countersteer. This means steering to the right as you turn left. As you enter a corner by leaning the bike to the inside and by applying power, the backend moves out to the right as it loses traction because the rear tire patch is reduced and the front end is loaded. You steer right so the bike doesn’t spin around in a circle and pitch you into the ether.

This whole business of sliding into and part way through a corner allows you to redirect the bike’s direction faster than a competitor who has to drive around a corner with an unaltered frame. Your straight line drive and acceleration distance will be longer than his and you will beat him to the next corner, all other factors being equal. If you don’t know how to ‘slide’, you will be able to learn it with my kit and experimentation during pre-race practice. A little note here. If you are a “slider”, cut off a portion of your frame’s steering stop on the right side. Stop cutting when the trees are about to smash into your tank.

Other steering options

There are vendors out the offering insanely priced “trick” triple trees. More often than not these products only move the fork out or in from the steering head, but maintain the stock fork angle. Ain’t gonna work too slick. This can help in some track conditions but does not make steering easier or faster. The only way quicker steering can be achieved is to alter the fork angle.

We are the only company to develop a simple and economical product for better dirt track cornering. Few have done it inside the steering head. And nobody has done this for a Sportster.

Buy my kit. It will help you win, especially against stock Sportsters and maybe those pesky Indians.

Handling formulas for Sportster dirt track racing

Recently I went off the deep end to report the handing characteristics of some of my products in various combinations:

  • Longer shocks
  • My Sportster Racing QuikTurn 27° Steering Kit©
  • Davey Durelle race kit for sportster forks
  • My new race style fork brace

Achieve Race Handling

  1. Stock Sportster forks are soft for street riding but awful on the track. In race conditions handling is mushy and does not exhibit corning confidence. The best way to fix this issue is to have a company like Davey Durelle ’racerize’ the fork internals.

  2. The ideal fork angle is about 26.5 degrees. It’s good on the track and reasonably safe on the street. We found the best way to arrive at 26.5° is to use:

    1. My new 14 ¼” shocks
    2. My Sportster Racing Quikturn 27° Steering Kit©
    3. Durelle’s fork tuning kit
    4. My race style fork brace. Adds back an inch of travel over my street brace.

  3. Because of this research I am going to stop selling 15” shocks. Instead I’ll be ordering 14 ¼” shocks--better on the track and perfectly fine on the street.

Okay let’s study the variables and see where we arrive.

60" 29.6° OEM

Great road stability, awful on the track

60" 28° OEM
Stock triple clamp position
15" Okay on the street. No advantage on the track.
59" 27° OEM
1" triple clamp drop
15" Not a good race idea. Awful fork dampening made worse with reduced travel.
58.5" 26.5° OEM with 27° Quikturn kit 14-1/4" Ideal for flat track racing. Marginal street stability.
59" 25.5° OEM
Stock triple clamp position
15" Race only, but don't go this far. Unsafe on the street.

This is general information derived from accepted flat track knowledge. I am not advising or recommending any handling changes you make from OEM specs. The results of any changes are on you and you become responsible for any outcome, good/bad or safe/dangerous. You know racing is a dangerous activity because you do it and have observed (or have heard about) negative happenstances. My QuikTurn kit moves fork rake back approximately 3°.
