(See attached picture)The biggest change to the bike besides the sound was the way the Grom handles now, it changes directions like it lost 40 lbs up top instead of just the 5 lbs or so. It is a great feeling.The sound is great, but a bit too loud without ear plugs even with the decibel killer in. I am 38, so if you are younger it is probably just fine or too quiet. It comes with the "biggest" db killer that Two Brothers makes installed already. I emailed Two Brothers to confirm that it comes with the "biggest" one because someone on here mentioned you could get one that would lower the db even more, but no luck. It is as quiet as it will get. I think I will lose my hearing quick enough that it won't matter anyway. It was totally worth every penny for the handling and weight change alone, having a great sound that makes me redline it constantly is a bonus. No more making motorcycle noises with my mouth! ### ⭐⭐⭐⭐⭐ subtle, yet throaty. Sounds great! *by F***W on Reviewed in the United States on August 16, 2016* The fit and finish is great. I was worried about descriptions of it sounding like a dirt bike, but the exhaust note is excellent for this little Grom. It sounds like a classy little dirt bike that won't piss off the neighbors or get nasty looks. The tone is subtle, yet throaty . Very happy with this two brothers product! ### ⭐⭐⭐⭐⭐ Great product! *by E***. on Reviewed in the United States on November 26, 2019* Fast shipment and perfect fit. Makes the Grom sound like a 250cc and it really gives it noticeable more power! --- ## 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.vu/products/17887390-two-brothers-racing-005-3740105-s1-s1r-black-carbon-fiber](https://www.desertcart.vu/products/17887390-two-brothers-racing-005-3740105-s1-s1r-black-carbon-fiber) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-07*
