WHEETOYKART Harley Style Adjustable Cushion Backrest with Carrier, Pillion Backrest Cushion Support Compatible for Bullet Thunderbird 350,500,350x,500x Heavy Metal Used(Colour:Black) Latest 2021

It easily fits Thunderbird 350x, only thing is you have to remove the seat and you have to twist left-right and stretch the front portion. Sorry forgot take pic. I removed it again. Its only when I am on travelling.

Sturdy material. However, the paint came off after a small spell of rain.

It's not fit correctly on my thunderbird 350, the screw holes are in defferent position, I need to spend extra money for fixing that, and a paint job after that. Waste of money, local quality materials used.

This is a personal setup for a Thunderbird 350xSetup: setting this up is NOT a 10 min job. You will have to remove the tail light assembly and then slide this in. Two man job.Beware to use 12 mils nuts to hold this in place.Onece it is fited reassemble the tail light.Preferably take it to a mechanicBack support assembly: you can assemble the back rest in 2 ways; frond mounting or rear mounting. Difference will be in milimeters but depending on what you need it for can make a difference.For max pillion comfort mount it from the rear, it will reduce your luggage area slightly(insignificant for most). For extra luggage capacity mount it from the front. For maximum luggage capacity do not mount the back restPros: good mounting hardware for top cases and soft luggage of megium size. The back support is amazingCons: fitting is a two man job usually will require mechanic assistance

Very Good Product. Really loved it.Delivery was one day in advance. Totally worth for what we are paying...Fitting was really easy.....but caution , that removing the original backrest is a big pain....due to the design the tools don't reach the nut and removing it take lot of effort......once the original one is removed, fitting this is one is a cake walk....It's very sturdy and fits very nicely on thunderbird.Kudos to the manufacturer.
