They do not sell any of the Thunderbird Models here in the US. How can I get the Thunderbird X handlebars for my Himalayan? I looked all over the internet, and haven't found them yet. I would rather do what you have, and just replace the bars. Thanks for your helpInstead of bar risers I just replaced the stock handlebar with the one provided in Thunderbird X model. Got it stock from RE, good quality. Its a direct fit and no major cable tension. Also, since it comes in black, it preferred.
Alternatively one can get extra top bracket of current Himalayan handlebar, and longer bolts. Reverse 1 bracket and place it under the handlebar, it rises the handlebar. the longer bolts are needed due to the increase in height. Comes cheap too.
