How I converted my Himalayan 450 tyres from tube to tubeless

A Bajaj Avenger's tube, tyre sealant and 2 psi over-inflation are all that's required.

BHPian khan_sultan recently shared this with other enthusiasts.

Tubeless conversion using TUBE FLAP.

I will eventually buy the tubeless rims when they are available and till then the tubeless conversion was one of the things to be done.

Options considered were way2speed, out, and simple formula-X type sealant in the tube. Somehow stumbled upon the tubeless conversion using a tube flap inside and it looked simple and promising enough.

I thought of giving it a try for the reason that it seemed a simple enough job, the least time involved, and the most cost-effective with a worst-case scenario would only mean losing a set of tubes.

The difficult part was getting hold of a shop/mechanic who could do this with some skills (as no one these days likes working on tube-setup motorcycle tyres) and finally managing a HIGH FOOTFALL puncture shop as the skill of dismantling & putting back the tyre/tube is the most important skill needed here.

For the rear, the Avenger 15-inch tube (130/90-15) works best, and for the front, the stock-size rear tube works (a 1 or 2 smaller size is helpful as the tube will be a tight fit and that is very helpful). Got tyre sealant also added finally for supposedly extra peace of mind if a puncture happens.

Here are some of the pictures of this work:

Finally, the extra portion of the tube flap is cut, ensuring that a very small portion remains outside.

The same procedure is used for the front.

I think one precaution to take would be to ensure that the tyre pressure does NOT FALL DRASTICALLY and may need checks till one is comfortable with the setup. Let's see. For now, have overinflated the tyres by 2 psi on both.

If one needs to "replace" the tyre, then obviously, this whole exercise will need to be done again. Essentially, any time a tyre needs to come off the rim, this exercise would be needed again.

Summary: Is it the best option? Maybe not. But for sure is quick and cost-effective. To get back to tube type is just a matter of putting the tube back!

Will ride for a few weeks and observe how the air holds up and look out for any leaks/pressure drops.

Total Cost: 500 for Avenger tube + 850 for the tyre sealant + 750 labor charges
