Of all the Asian countries, Japan has the highest profile in the custom scene, and has even exported the whole genre of SR400 modifications. But other countries are getting more press now, with Australian shop Deus moving into Bali and the whole Indonesian scene gaining momentum. Now it looks like the turn of Taiwan, helped by classy new magazines such as Free Biker. This hunkered-down Sportster custom is called Guerrilla: it’s just graced the pages of Free Biker, and comes from an upstart new Taipei shop called Rough Crafts. According to builder Winston Yeh, “The initial idea for this bike was to get it to look custom, without being too ‘far out’—because Taiwan has a crazy regulation that all bikes bigger than 250cc have to pass an annual exam after they are older than five years. The bike is compared to the stock picture and if it looks too different, it will be hard to pass. With that in mind, I tried to create a bike that has similar profile to stock. So you probably think it’s ‘normal’ from far away, but you can see the customization when up close.” The bike takes Harley’s Nightster theme a step further, with a chopped front end, new bars, bodywork and lighting—and a terrific exhaust system that adds to the compact, muscular vibe. Excellent work from a builder worth keeping an eye on, so check out Rough Crafts’ blog for regular updates.

    Hello Winston !
    It’s beautiful work, one of the most beautiful bike I’ve ever seen!
    I have an iron 883 that I want to customize, and I confess that I will draw your creation.
    I can not find the coker tires 5.10×16 “, you could tell me more about the specific references front and rear?
    Then I wondered if you had changed the angle of the fork?
    Is it possible you order parts?
    Thank you in advance

    Hello Winston! I love this Guerilla bike… I am looking to get that headlight and those triple trees. How much did you have to cut off of the forks to get the front and rear to be level and what wheel did you use for the front? Is that a stock rear wheel? Thanks!!! I lived in Taiwan for 2 years in Beitou, loved it so much, want to come back!

  7. Peter says:

    Hello I’m wondering What the set up is on the front end of this bike ie:The tree’s, axel size, and did you use the stock rim? Also did you need to make any changes to the rear end to fit the large tire? And my final question is where did you find the tires I can only seem to find Coker tires of a much smaller size. Thanks alot….and awesome work!

  8. Jimmy V says:

    I too am looking for info on these tires. I have a 2001 XL1200″S” model that I am looking at slapping a fat tire set on but don’t know if I can do it without mods. I would rather leave the suspension alone if at all possible. Can you please email me some info. Thanks!

    Hi, the best looking sportster i have ever seen , i have a v rod and even thought of doing a sportser now lol

    anyway a good friend has a sportster and is interested in the big wheel look , i showed him yours and he fell in love . Can you tell me what size the front and rear tires are and maybe the make of the rims .
    Is that a stock front end or wider to fit that tire

    Hi Winston,

    Love it!You did an amazing job! I would like to know what the set up is on the front end of this bike and the rear.Those tires look sick! I’m about to by a new 2011 Forty-eight and would like to give it a similar look.. this is truly my dream

  26. Luke says:

    Your work is insane! I love the guerilla iron. Like many others messaging you, I too would like to know if parts are available to get the killer effect of the guerilla.
    You’re a legend

  27. Guillaume says:

    Hi Winston, I leave in Paris and was about to buy myself the Sporster 48. very inetrrested into your custom 883 iron which i beleive is an exceptional work you have made on the bike. this beeing said i would love to create something alike. What would be the best option available, start with the same base bike (i.e the 883 iron) and have you send me the parts to make a similar bike or start with a new project with you to customise a 48 sporster. i kind of like the base 48 Sporster but open to your sugestion. looking forward to hear from you Guillaume

    Love your build. You really took a good looking bike to bad ass. Great vision. I’m interested in parts and pricing for converting the front end of my bike to accomodate the larger tire and wheel. Can you email what you have for sale or places I can purchase similar tires front and back and wheels if needed. Also interested in the pipes.

  31. Matheis says:

    The best looking sporty, bar none. Seriously phenomenal work. Could you please email the front end components I will need or have to mod in order to get that straight, fat look. Thank you so much. Again, sick bike.

  32. Josh says:

    Man I can only imagine how this thing sounds. Truly a breath of fresh air seeing such a common bike turned in to something so unique. If you had an online catalog you would have a lot of happy customers, judging by these comments. Truly awesome work.
