Review: Fantastic Model! - Met or exceeded my expectations for quality, ease, and beauty. Quality - Mostly great. No missing parts. Only three small fit issues. (1) one gear needed to have its center hole bored out. Not a big deal, took two minutes with a hand drill. (2) one mounting tab for one valve rocker was bent too tight, keeping the valve from closing. I put that head on the non-display side of the engine. (3) The gearbox shifting action is iffy. Lots of thin plastic parts with loose fit. Be deliberate but careful and it mostly works. Ease - Instructions were clear and detailed. Great diagrams, good pointers for routing, alignment, and sprue trimming. Beauty - All parts have fantastic surface quality. The chrome exhaust really shines, all the translucent panels are clear to see through and don't distort things. Final note - It doesn't have a clutch. Review: Amazing detail and quality - The quality and precision of the molded pieces was a pleasant surprise. I didn’t have any issues with assembly, the pieces fit together perfectly. The quality of the instructions reminded me of the factory manuals I use to maintain my own BMW R90S. The whole assembly will take about 3 to 4 hours at a comfortable pace and few breaks. The book included was filled with interesting facts about the history of the boxer engine and the R90S. Being an owner of an R90S I was particularly drawn to this model because of the advertised accuracy. The engine housing and gearbox are see through and you can see the relationship between all the internal components. The ‘spark plugs’ light up or fire in the correct timing. There is even an alignment tool that ensures that the timing belt is installed with the pistons and flywheel in the correct positions so that the spark plug fires when the piston is in the right position. To top it all off, the gearbox actually shifts between gears including neutral! I would recommend this to anyone regardless of your skill level. The most difficult aspect of this project is removing the waste plastic where it’s attached to the mold remnants. I’d advise a pair of electrical wire snips that cuts all the way to the tip to cut parts free then trim them with a razor utility knife. The plastic is too thick to cut safely with just a utility knife. Be careful not to get fingerprints on the inside of the clear plastic. These can’t be removed once assembled. I can go on and on praising this product, in summary this is an extremely well designed, precision, functioning model that does an excellent job exhibiting the internal relationship between the moving components of a boxer engine and transmission. ## Features - Includes museum issued collector's manual.

Made in China, BTW. **Q: Beautiful kit. but the wire that activates the piston lights is about two inches too short. is there a remedy for this?** A: Try different routings - I found one that just barely made it - plug the wire in first, then mount the motor on the base. Alternately, cut the wire, solder in an extension as needed. **Q: Is it pretty cool, It looks so badass ?** A: Extremely cool. I have a collection of model engine kits and this one fits right in. **Q: Box size** A: The box dimensions are 21x14x7 inches. Cheers!

Everything fits. I put mine together in three evenings. *by E***K on March 1, 2021* I've had BMW bikes with boxer motors since 1975, including the R90, and am very familiar with the engines and transmissions. This model is very realistic, inside and out, and is actually is as good as it looks online; it did not disappoint. Very well made, great precision. Everything fits. The transmission even shifts through all five gears. I put mine together in three evenings. It even comes with a very nice coffee table book about the history of the BMW bikes, and the assembly instructions are also in this book. The only tool you need to provide is a pair of nippers (I used a sharp pair of flush diagonal cutters, which worked well). The kit includes a small Philips screw driver, which did the job nicely. Everything is held together with small screws of one size. No glue required. ## Frequently Bought Together - BMW R/90-S Flat Twin Engine Model Kit with Collector's Manual - Franzis 1965 Ford Mustang K-Code 289 V8 Engine Model Kit with Collector's Book - Updated 2023 Version - Rustark 21Pcs Modeler Basic Tools Craft Set Hobby Building Tools Kit for Gundam Car Model Building --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/117200616-bmw-r-90-s-flat-twin-engine-model-kit-collectors](https://www.desertcart.pe/products/117200616-bmw-r-90-s-flat-twin-engine-model-kit-collectors) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-08-08*
