1:58 You don't measure the depth of the tread right over the tread wear marker. Unless you're trying to sell more tires. That "hump" at the bottom of the tread groove is the wear marker. When it gets flush with the surface of the tire you've used up your tire. If you're using the gauge over the top of the marker you're going to throw away a tire that still has plenty life in it.
@@optikforlife Well, Michelin disagrees with you. This is directly from their website: "When the tread wear level reaches the wear indicators (which define the legal tyre limit), it is time to change your tyre." It's from the UK website, but they also say that the min legal limit is 1.6mm.
@@johnnyblue4799 no, you are looking at car tyres. "Motorcycle tyre wear occurs for all tyres over time. Care should be taken not to exceed the legal wear limit. The wear indicators on the tyre are 0.8 mm high. This height is strictly the same for all tyres. Although the wear indicators provide information on the level of wear, it is important to know that this is an indicative value which does not always reflect the legislation." - Michellin UK website
@@optikforlife Indeed. My bad for assuming it would be the same. "The legal limit varies from country to country. For example, in France, the legal limit is 1mm, whereas in Germany it is 1.6mm. In the United Kingdom, the legal limit for motorcycles over 50cc is 1mm across 3/4 of the width of the tread pattern and with visible tread on the remaining 1/4. For motorcycles up to 50cc the law requires that all the grooves of the original tread pattern must be clearly visible." - Michelin UK. Regardless, if you measure the depth over the TWI, as shown in the video, you need to add 0.8 mm to the reading, or you're losing 0.8 mm of tire life, which is not negligible, I think. You made me more aware of the legal issue. Thanks.

yes and no, the hump is 1mm marking, in germany for example 1.6mm is the minimum, so you need to change before the hump is flush.

Why do you show a tire that was used at a track day and suggest inflating it by the manual? Nobody uses 36/42 PSI at the track. Or I hope not.
Big fan ❤❤ Kawasaki motors
Make a 270 crank bikes instead of ninja 650 and z650 it would be perfect.
Hello kawasaki make a kawasaki ninja h3 😅😅
You should use nitrogen
