Everything fit well and the motor started up and ran well on the second kick. I wish the kit came with better instructions though. I spent a great deal of time searching in a service manual and on the internet for torque specs and information on how to properly set up the kit. For instance they make no mention of setting ring end gap for the kit. The service manuals talk about how to do this but it was not until I called the manufacturer that I found out this was already set. Overall a great kit. It added a substantial amount of power and the kit was well put together. Review: Complete quality kit - This kit was complete minus the side cover gaskets. Installation was straight forward but a manual will help with torque specs or if you’re not familiar with these XR engines. Played with the jetting a little and ended up with a 40 pilot and 108 main. Modified the air box by drilling the top and side cover to allow more air flow. Modified the stock exhaust as well. All in all I’m very happy with the end results. ## Features - Kit Includes: BBR aluminum cylinder, piston, rings, piston pin, clips, performance camshaft, heavy-duty valve springs, rockers with tappet adjusters and gasket kit ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | BBR Motorsports | | Brand | BBR | | Model | BBR Motorsports 411-HXR-1001 | | Item Weight | 4 pounds | | Product Dimensions | 11 x 6 x 1 inches | | Item model number | 411-HXR-1001 | | Is Discontinued By Manufacturer | No | | Exterior | Painted | | Manufacturer Part Number | 411-HXR-1001 | | OEM Part Number | 411-HXR-1001 | ## Images ![Motorsports 120cc Big Bore Kit with Cam 411-HXR-1001 - Image 1](https://m.media-amazon.com/images/I/71IiHLtT8BL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing Quality Big Bore Kit *by B***N on October 24, 2021* The quality of the kit was fantastic.

Installation was straight forward but a manual will help with torque specs or if you’re not familiar with these XR engines. Played with the jetting a little and ended up with a 40 pilot and 108 main.

I bought a 2006 CRF 100f for my Son about six months ago the motor was locked up and I about factory parts to Rebuild it with. The piston was froze up in the cylinder. I had to bore out the cylinder by hand with a cheap three blade hone. Simply because I couldn't find anyone to hone that small of a cylinder for me. being cast iron that took a good while to accomplish. the bike run pretty good and had a good compression. The bike run good for about six months and the cylinder started to egg still had very good compression and run very good just started to smoke. I spent about $300 on the factory parts to rebuild the engine to .025 over. I should have went the BBR kit to begin with. This kit was so easy I should've went this route to begin with not to mention the amount of power it did add to the bike. Don't get it confused it didn't turn it into some monster racing machine that a 10 year-old cannot ride any longer. But there is a noticeable power gain. It took us about 4 hrs to install. But that is in a shop that is set up to do that. It is a mediocre task if you're not familiar with engines and how they work. All I can say is do not waste your time on boring cylinders that smoke by this Kit and be done with it. Seller shipped right away as well. ## Frequently Bought Together - BBR Motorsports 120cc Big Bore Kit with Cam 411-HXR-1001 - Permatex 80037 Valve Grinding Compound, 3 oz. - MOTO1988 Engine Valve Set Exhaust Valve Intake Valves For Honda XR100R XR80R CRF100F CRF80F NSF100 XL100S XL75 XL80S XR100 XR75 XR80 OEM 14711-152-000 14721-176-000 --- ## 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.hr/products/2344918-motorsports-120cc-big-bore-kit-with-cam-411-hxr-1001](https://www.desertcart.hr/products/2344918-motorsports-120cc-big-bore-kit-with-cam-411-hxr-1001) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-17*
