I am obsessed with acquiring an extended swingarm and I know the MAX I would consider would be plus 8 in. I was playing with drawing program and moved my wheel rearwards approximately the same as diameter of the wheel. TrailBuddy doesnt know anything about their 6in swingarm having never sold one and has no mfgr data, alloy data... I have asked for dimensions as proof as to what it fits and the weight. I am afraid of someone welding up a swingarm using a soft non heat treated aluminum alloy. ie what soft drink cans are made of. In any case I found about fifty different pics of Z50s with swingarms but very few with exact details as to which manufacturer and exact length. I will soon create a photo gallery of all the swingarm examples with an external link as the result of all my research. I found several pics of swingarms swapped from other honda models but some require modification and I dont know what the exact lengths are or whether they heap on a lot of added unnecessary weight. My simulated photo was created with fifteen minutes of figuring out how to use "Paint" in Windows 10. Paint now has some 2D and 3D drawing capability. The bike used seems to be nearly the same model as I have. BTW....If you think the picture looks extreme...... I believe the new 2019 Monkey with 125cc has a 45 inch wheel base and IF I were to add an 8 in Swing arm as shown, the new wheel base for the Z50 would be 43 inches. I guess appearance is all about "proportion" Honestly I care mostly about handling and ease of riding and expect that I will be riding somewhat of a franken monster but not so much as some others that I have seen like the Hill Climb z50 machine which probably had 24 inches or more. of extension. What is important is the ability to return to stock format for value purposes. What do you think ?
