Let’s cut right into the art of a motorcycle

Here’s a bone 94 Shadow VLX

Let’s see what all we can do one.

There are many available to achieve a desireable and I will touch on seven of here. Please note these methods will on any bike, foreign or domestic. parts sources listed are for applications, if you have to ask where to aftermarket HD accessories, I probably explain. pun intended, there’s aftermarket support for Harleys a dozen people can shake a at.

First up is the cheap and easy and it doesn’t alter the frame so any warranties/current retail values on the are unaffected. It won’t get you the Easyriders America look, but for fans of his companion Billy this take you far. This method is one I like to call the per inch formula.

What entails is lowering the rear end raising the front and nothing For every inch you can lower the you can add one inch of fork length up

Depending on the design of your swingarm and suspension (and how of that suspension you wish to you can typically go anywhere from 3 to 6 lower in back. Lowering the typically involves acquiring a kit (available in the aftermarket for most mid and larger cruisers), modifying the OEM shock(s), aftermarket shocks, or out the shock(s) for some fabricated rear struts.

The solid can be easily made after the is removed, simply acquire steel (square tubing for bikes, flatter stock for shock rear ends), the swingarm where you want it in to the frame, measure your points, and drill holes in metal and voila: instant If you really want to get fancy, the shock bushings and drill holes big enough to accept as this will help some of the vibes.

Granted rubber bushing will be only dampning available. but one approach to the hardtail mod is to let some air out of the tire, some go as low as 15-18psi but I 20-25 myself. The partially tire acts as a shock making the ride a little boingier. That’s a technical look it up if you don’t believe me. One hardtail method is removing the and suspension and designing your own rear end, welding it to the OEM

Please read my Lowering ( Click for Lowering Info ) for info on lowered suspension and its on handling. And one word of caution on rides, forget what you about proficient cornering. and corners will need to be slowly, as any bumps in the road can your rear skipping and along causing a loss of If you habitually try to beat every light in right turns, isn’t the mod for you.

Bumps and can send your tail too, and rough roads can your fillings loose. All in all is a barhopper’s mod, but if you’re to sacrafice good handling in the of style, nothing looks than a slammed rear end and a fat stuffed up into the fender. lowering kits can be had from manufacturers including Highway Scootworks, and Cobra.

One good for modifying OEM shocks is Sons of Metric Cycles, and SOTMC and also carry hardtail for some models.

Now that we the rear end covered on the inch per formula, it’s time to the front. To add fork length you can fork extensions for some Fork extensions are simply top with a little extra to them, they replace the top cap a 2 to 6 inch long piece of matching fork tube.

But for integrity, actual longer tubes is your best Forking by Frank has been longer OEM fork tube since the dawn of the chopper age way when, and you can order any length of tube (up to 10 over stock for just about any motorcycle in or not. And one final option to the front is going up to a larger wheel, if you graduate from a 19 rim to a 21 this can add another inch to the and few things look better on a than a 21 inch front

One final word on the inch per method, by making these you will be tilting your rearwards so your frame increases the more extreme you go, increasing trail. Slow handling will suffer but rides will be straight and your center of gravity is moved further rearward. As an bonus straight line will be more controlled the front end won’t dive as

This VLX owner went for the tilt 4 hardtail slam out and added 4 fork extensions, the turn signals covering the

The next method to chopping up a good bike without the frame is by swapping out the OEM triple with a set of raked trees. In to looking great, raked add a few extra degrees of slant to the The downside to this is trail and if you don’t have much to begin with raked can make a bike very Please read my Frame editorial ( Click for Frame Info ) for more information on how and trail works.

Raked are typically available in a +3 to +7 degree although I’ve seen that add as much as 12 degrees of Raked trees by themselves place the bike into a forward stance, and if you read Lowering editorial you know this unbalances the bike in the way.

Hence, depending on the original rake was before the trees were added, and how extra rake the trees are going to have to make an per inch modification to the bike in the of either lowering the rear or the front, one to three inches on end being the typical mod here. do the research before slapping a set of trees onto your there are several online calcualtors. I like the ones at RB and Perse Performance.

On my 92 VLX I went +6degree trees, 4 over and a modified rear shock

up on the chopping block is modifying the Please check with dealership about warranty and price values before this mod, as it can serve to or affect both. This mod also affect your premiums. remember when you getting your quote asked if any modifications were to the motor or frame?

There ya go. Anyways, this is the old way of making a chopper (and this is how the name chopper to be)and is still in use today. Choppers shows one painless of adding some rake, but folks like to extend the and backbone of a frame when frame mods. What incurs is cutting the frame stretching them apart, and a sleeve in between that is and reinforced.

This sleeve is comprised of a similar diameter section with smaller welded inside, these portions are then inserted the frame. But some welders to reinfoce these extended tubes externally, by welding a length of support material the entire length of the modified tube. The end result is the steering is now positioned in a new angle, thereby rake (and trail).

is where the aforementioned raked really work, since the frame already boasts a trail figure the raked serve to bring this back down into a user freindly neighborhood. And also give a little slope to the already slanted Triple tree design a very important factor a modified frame.

This 88 Shadow recieved the hardtail and stretched frame downtubes with 8 over forks

Now the three major methods been covered, the fourth is to mix and match those processes, is inevitable. The most extreme out there do just that, the are modified for more rake, trees are added for both forking fun as well as making the more manageable, and the rear is nice and squatty to boot.

this isn’t an approach you do in steps, unless you have a wallet to continually replace along the way each time you a change. Nay, a lot of planning and goes into each of the mentioned methods, so it stands to that by combining them said research increases So plan accordingly.

For example, by the inch per inch formula, you can the rear two inches and add two inches of length up front. By adding trees to the inch per inch you can stick with the 2 over and have the front return to a position for the ground pounder or go with 4 over forks to the inch per inch stance and rake/wheelbase. Modifying the frame demands raked trees to a decent trail dimension, and forks is also mandated.

The owner of this old school chopper didn’t leave OEM parts untampered on his 2002 VLX

number five is a new one that hit the recently, a chopper conversion These kits serve to that combination style zero mods to the frame, and is reversible if for some strange you would ever wish to back to a stock ride. conversion kits include a designed set of triple trees artificially recreates a new steering as well as a new rake, along a set of longer fork tubes.

All is to spec for each particular so the end result is that radical and stretched out chopper look and These kits are well with safety and quality in and they sport superior That means they cheap, but you could easily the same amount of cash the combination approach yet all the mathmatics are out for you, and it doesn’t take as to get it all together and go for that first

Check out Seeger Cycle for info on such kits, have them available for Harleys and Metrics.

number six is an educational experience and cost a pretty penny This is the ground-up custom route, where you go to the aftermarket for everything. Frames, swingarms, ends, wheels, tanks and engines, you name it it’s out waiting for you to slap it all together to desires.


But this direction as much research as it does and construction time, as you don’t the wrong combination of parts. because this set of trees good in that magazine and frame looked good in magazime doesn’t mean it work together on your And the final result is a real to register, so keep any and all reciepts/bills of

If you can score someone’s half-built that they gave up on you can in where he left off and save a of time and money. A slightly route would be the kit bikes, or in a box. Check out the various HR3 kit in the Custom Chrome catalog, you can get a kit that works right and good starting at $13,000 and up, less than the asking of a used Hog.

Getting a on a kit bike is easier than a build, but not as quick and painless as it be with a factory production

The owner of this trick shelled out some coin to it, but it was well worth the time and

And of course the last way to get a chopper is to buy one is already built. There are factory designed/constructed bikes out with names like Ironhorse, Bourget, Big Dog, and West Coast Choppers to a few. Since these are built designs, they with a VIN and it’s no different buying a Harley or Honda it comes to registration time.

Or you even pick up someone ground up custom build, the builder already registered and it then it comes with a But you’re also trusting his and construction abilities too, the factory jobs that are done you stand a chance at someone’s frankenbike that like an intoxicated pig on a frozen

In closing are a few things I’d like to out about the chopper mod. Do the before buying your part(s). Lots of it. Especially rake and trail. Make you have everything you’ll for the transformation before turning first wrench, after all you want to have the major done and then find out you a longer brake and speedo

This means you’ll be to drool all over an unrideable while those parts are delivery somewhere in Podunkville. a second bike to ride is beneficial. Aftermarket parts to spec doesn’t neccessarily into quick and easy simplicity. Expect to run into along the way, one company I with was so far off in every respect my Shadow I think I would had an easier time adapting parts.

Aftermarket parts compatibility the only issue to contend in some cases your ends up being too long and the will be parked in a near stance, so be prepared to modifiy or that too. While kind of modification can be easily on a beginner bike, it isn’t a mod. A chopper is to the new cruiser as a 600+cc supersport is to the new sport They handle much They brake much

They corner much In other words, get some saddle time in on your bike before considering a Besides, with a long you’ll never pass the DMV portion of the license test it comes time for the slalom the cones.

And leave early for because while the front may be on time you’ll be five late.

Keep your in the breeze.
