Smoother gear shifts was the immediate benefit
I put half a bottle in to my bike in 2024 and immediately benefited from a smoother gear change. After an oil change in 2025 I used the other half of the bottle. The reduction in friction in the engines internals is the benefit here. I think there is a small improvement in MPG but I couldn't quantify it. I'll certainly be using it again.

100% works.
I was a little dubious about this stuff, but my (all) BMW F900 engines are quite noisy, so I thought I’d give this a try. I put in the correct amount for a wet clutch & went for a ride. After 15 mins the engine definitely sounded better, less mechanical noise, & just generally sweeter. After 30 minutes I also noticed the gear changes had been smoother. Overall I’m delighted with the results.

Used on Triumph sprint 955i
Was very sceptical about oil adaptives but having a first jen triumph 955 that are notoriously noisy especially on tickover thought I'd try this as it was recommended by of a couple of friends that have used it in their bikes. Using the recommend amount of 20 mm (measured with a syringe) for wet clutches whent for a ride and almost five to ten minutes could tell a difference. After about 45 minutes of riding when all up to temt and mixed in I can honestly say I can tell what I would say is a big difference. Gear changes are hugely smoother, seems to spin up a lot nicer and generally vibration from engine on tickover and riding are smooth and crisp and no problems with clutch slip. I would recommend this for any one as long as you use the right amount and you'll have plenty left for oil changes or another bike.

better than i expected...
While i am a big fan of Liqui Moly products (oils, cleaning fluids) - honestly i bought this one when it was on offer alongside some fresh oil and filter for my winter service schedule. It was a few quid and i thought " why not" . its a strange substance to use - very thick and if you try to measure it (as i had to because its a wet clutch) it 'sticks' to the measuring surface which is a bit annoying. from the first ride out in spring it made the gearbox feel significantly better! - its in a 2015 triumph speed tripe which i had really considered to have quite a clunky 'box. This has made shifts significantly better - much better than i had expected an additive to make. I've no idea what it has done to the rest of the engine, but the change to the gearbox is so good that i will definitely use this again!

An excellent product and must for every motorcycle.
I use MOs2 for my Suzuki Vstrom, and must say that it has worked amazingly on the internals of the engine. Every things is running butterly smooth. Just done an annual service from an authorised suzuki dealer, but there was still some vibrations in the bike. As soon a put MOs2 into it, the vibration almost disappeared and the bikes now giving a better fuel efficiency as well.. I would highly recommend this product. Please give it a try and see it for yourself.

Una piccola spesa per una grande protezione: un "must have" ad ogni cambio olio
Da motociclista attento alla manutenzione e alla longevità del motore, ero curioso di provare questo famoso additivo della Liqui Moly, un marchio che è già di per sé una garanzia di qualità. Dopo averlo aggiunto al cambio dell'olio della mia moto, posso confermare le tante recensioni positive: è un prodotto che, pur non facendo miracoli visibili, offre benefici tangibili nella guida e una grande tranquillità mentale. PRO: Maggiore fluidità e silenziosità del motore: Il primo effetto che si percepisce è una maggiore "rotondità" e fluidità del motore, specialmente a freddo. Le vibrazioni sembrano leggermente smorzate e la rumorosità meccanica generale (es. ticchettio delle valvole) appare più contenuta. Cambio notevolmente più morbido: Questo è il beneficio più evidente e apprezzabile nella guida di tutti i giorni. Gli innesti delle marce sono diventati nettamente più morbidi, precisi e silenziosi, con meno "clank" meccanici. È assolutamente sicuro per le frizioni a bagno d'olio; non ho riscontrato il minimo slittamento, solo una maggiore fluidità di funzionamento. Protezione anti-attrito (il vero scopo): Al di là delle sensazioni immediate, il vero scopo di questo additivo (a base di bisolfuro di molibdeno, MoS2) è creare un film protettivo ad alta resistenza su tutte le superfici metalliche in movimento. Questo riduce l'attrito e l'usura, specialmente nelle condizioni più critiche come gli avviamenti a freddo o l'uso intenso. È un investimento sulla durata del motore. Facilità d'uso: Basta versare il contenuto del flacone nell'olio nuovo al momento del cambio, seguendo le semplici dosi consigliate. La confezione da 125 ml è sufficiente per diversi cambi d'olio, a seconda della cilindrata del motore. CONTRO (o meglio, precisazioni): Effetti più evidenti su motori con qualche chilometro: Se avete una moto nuova di zecca, potreste non notare differenze eclatanti, perché il motore è già in condizioni ottimali. I benefici si apprezzano maggiormente su motori con qualche anno e chilometro sulle spalle, dove l'effetto "levigante" dell'additivo si fa più sentire. Non è un riparatore di motori: È fondamentale capire che questo è un additivo per la manutenzione preventiva. Aiuta a mantenere un motore sano in condizioni ottimali, non a riparare danni o problemi meccanici già esistenti. Conclusione: L'additivo olio per moto della Liqui Moly è un prodotto eccellente che consiglio caldamente a tutti i motociclisti che tengono alla salute e all'efficienza del proprio mezzo. È una piccola spesa che, ad ogni cambio olio, offre una protezione extra, migliora sensibilmente la fluidità del cambio e dà la tranquillità di aver fatto il possibile per preservare il motore nel tempo. Per me è diventato un appuntamento fisso a ogni tagliando. Consigliatissimo.

!!Can be used with a wet clutch!!
My first delivery arrived on time but damaged causing contents to be deposited in the packaging. This was corrected and delivered the following day. I have used this in my Dealim Daystar VL125Fi motorcycle with 25000 Kms on the clock. It was beginning to become a little noisy the usual engine rattles and wear noises. After using tis with new oil and filter it was much quieter, within a week the bike felt much smoother and runs almost like new. Highly recommended but read the dosage instructions carefully. !!Can be used with a wet clutch!!
