Review: Perfect fit, easy install - Installed in less than ten minutes (seven of those involved looking for my Allen keys) and was a perfect fit on my 2017 R3. Works better with my helmet that has the ring attachments (HJC) than with my slide-click-lock one (LS2), but I just slip the hook through the straps between the buckle and the adjuster slide and it works just fine. After I got it installed, we started looking for them for the other bikes, but couldn’t find any for those models (GS500F, SV1000S, and CBR1000RR) but are hopeful the product line will expand. 10/10 would totally recommend. Review: Not the best quality but I think it'll work. - It looks okay it's kind of flimsy feeling. And the paint quality is very poor. I literally tapped it and the paint just flaked right off. Otherwise I think it'll slow down anyone from just grabbing my helmet when I go into the store for a couple of minutes. As far as fitment, it fit fairly well ## Features - * Fitment: YZF-R25 up-2019, YZF-R3 up-2020, MT-25 up-2020, MT-03 up-2020 - * Aluminum and Steel - * Item is easy to install and includes instruction - * Packing included: One set of the Helmet Lock and 2 Keys - * Condition: 100% brand new ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | GUAIMI | | Special Feature | Anti theft | | Lock Type | Key Lock | | Material | Aluminum | | Recommended Uses For Product | Motorcycling | | Style | Modern | | Color | Black | | Number of Pieces | 1 | | Controller Type | Hand Control | | Manufacturer | GUAIMI | | Item Weight | 8.2 ounces | | Package Dimensions | 11.81 x 3.5 x 1.46 inches | | Manufacturer Part Number | Toukuisuo-R25 | | Special Features | Anti theft | ## Images ![Motorcycle Helmet Lock Anti-Theft for YZF-R25 up-2019 YZF-R3 MT-25 MT-03 up-2020 -Black - Image 1](https://m.media-amazon.com/images/I/51gC6Tg+0hL.jpg) ![Motorcycle Helmet Lock Anti-Theft for YZF-R25 up-2019 YZF-R3 MT-25 MT-03 up-2020 -Black - Image 2](https://m.media-amazon.com/images/I/61E-ZWtbjFL.jpg) ![Motorcycle Helmet Lock Anti-Theft for YZF-R25 up-2019 YZF-R3 MT-25 MT-03 up-2020 -Black - Image 3](https://m.media-amazon.com/images/I/41saNytRgGL.jpg) ![Motorcycle Helmet Lock Anti-Theft for YZF-R25 up-2019 YZF-R3 MT-25 MT-03 up-2020 -Black - Image 4](https://m.media-amazon.com/images/I/41MDCM4BXHL.jpg) ![Motorcycle Helmet Lock Anti-Theft for YZF-R25 up-2019 YZF-R3 MT-25 MT-03 up-2020 -Black - Image 5](https://m.media-amazon.com/images/I/41Nn4mC-WyL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect fit, easy install *by K***. on November 7, 2019* Installed in less than ten minutes (seven of those involved looking for my Allen keys) and was a perfect fit on my 2017 R3.

And the paint quality is very poor. I literally tapped it and the paint just flaked right off. Otherwise I think it'll slow down anyone from just grabbing my helmet when I go into the store for a couple of minutes. As far as fitment, it fit fairly well ### ⭐⭐⭐⭐ Solid lock for low-level security *by T***. on November 8, 2019* Installation was easy. I like that the screw that attched the lock portion to the bracket is protected by the latch when closed. The locking mechanism does feel a bit flimsy, however, so I'm not sure how well it would hold up to someone really pulling on it. Additionally, if someone wanted to (and had the right sized hex wrench with them) they could just take the bracket off entirely. None-the-less, for the price this provides much better security again low-level attacks than leaving a helmet unprotected would. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/140399423-motorcycle-helmet-lock-anti-theft-for-yzf-r25-up-2019](https://www.desertcart.us/products/140399423-motorcycle-helmet-lock-anti-theft-for-yzf-r25-up-2019) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
