Silkolene 4T Pro-4

Just changed my Vstrom 1000 oil and used Silkolene for the first time. I haven't noticed a change in performance but time will tell. The cost is much less than bike store synthetics.

Red Cough Syrup

Had to turn my clutch adjuster out 1 full turn, this stuff is super slippery I guess? Oil analysis reviews on Silkolene products have been very good, rates higher after 2k miles than Motul. Only drawback I see is the 10w in winter temps is like molasses, so i would be cautious in colder temperatures.

Piece of Mind:

Worth the extra dough. It's so-- not enough O's in smooooth.

Not enough O's in smooth

GREAT stuff, but pricey. Put it in my 2010 Z1000 and "old school" 1999 Su SV650. Noticeable improvement in both.

My Bike Bleeds Red...

I'm running this in my Triumph Tiger 1050 and the engine shifts noticeably smoother than it did with Repsol full-syn before it. My thermostat is also running cooler than before (it doesn't give specific temps, just a bar graph). Right now I see no reason to switch oils, and Silkolene is race proven so just knowing that instills confidence. Plus, having a Brit bike means dealing with leaks so at least now my bike will bleed red!

4t 15-50

Absolutely 100% recommended but price is to high. Lower your price and you will put every oil company out of business.

A Difference?

I was a little shocked at the red color. I notice no difference in shifting smoothness. But, gives me piece of mind having a quality oil in my ride.

Silkolene Synthetic MC Oil

Great oil because the bike shifts a whole lot smoother. The 15w50 also protects against high summer heat better than a 5 or 10w40. Liter bottles are super since my British Hinckley Triumph holds exactly 4 liters or I guess 4.4 US quarts. My Triumph dealer also uses Silkolene in all his Triumph oil changes

Worth every dollar

Been using this in the track bikes for several years now. Holds up very well to the engine abuse and hard riding conditions. The last technician who performed a valve adjustment on my 636 could not believe how this oil coats and sticks to everything. It's superior to anything I have used in the past and I will continue to pay the extra money for that kind of protection.

great oil

I was hesitant at first cuz of the price...def not used to paying that much for oil but well worth it. I didn't think it would make that much of a difference...i was wrong. It shifts so much more smoother now it's unreal. Def recommend.

Engine runs a bit hotter than with Motorex synthetic

In the summertime, my engine ran at about 180 degrees F with Motorex synthetic. In the wintertime, my engine runs at about 185 degrees F (similar riding) with Silkolene synthetic.

Silkolene 4t Pro-4

This what you should put in your sportbike if you truly care about it. Going to track days with my '03 R6, knowing oil is not a problem.

Great for triumph daytona

Changed oil in my 09 daytona 675 from mobile 1 4t 15-50w to this silkoline 15-50w and what a difference. Made engine, shifting, and clutch very smooth. After a couple hundred miles seems like very good oil so far.

Great Oil for the GSX-R750

I have been using Silkolene for the last 4,000 miles and have noticed improved shifting performance. No oil consumption and holds up well even with a couple of track days thrown in.

Silkolene - 4T Pro-4

First time using this product so I don't have much to say right now about it. I have heard good things about Silkolene from some friends I do open track days with.
