I've bought this filter and I think it's cheap for this money. The photo shows a used filter, you'll get one that's completely white in colour. The filter also fits for the 750 cc and all models that have the bug eyes on the right and left side. That's what a new filter looks like. It's held by one tiny screw and it takes only 15 minutes to replace the filter. The first time you can clean this filter with pressured air, but when it gets too dark, it's better to replace it.
I purchased this helmet based on it's brand, functions and price. Everything has been perfect. The sizing is correct, and while I initially had concerns that my measurements might be wrong they were correct compared to the helmet size. The helmet is really a good helmet and Webike service, follow-up and delivery was excellent. I will definitely want to use Webike for future purchases
The only supplier that I could find in Thailand who were prepared to source and deliver a Michelin city grip 2 rear tyre to suit 155 Aerox. Lead time was rather long but webike were honest and apologetic in regard to the delay, and were VERY fast in replying to any questions in regards to the product.
