No it is not good for a motorcycle engine - to many corrosives that will cause negative impact - flush out and refill with either 50/50 distilled water and motorcycle coolant or temp lowering motocycle coolant

zip Ty Racing has a great product for this

Makes zero difference as long as it's ethylene based. Stop and think about it, what's so different about an all aluminum motorcycle engine and an all aluminum auto engine?? Hint: nothing.

Peak anti-freeze tried to sell us on the "don't use car anti-freeze in your motorcycle" BS years ago, and failed big time.

Feel completely confident in using a standard mix of 50% automotive coolant and 50% water (yes ~ distilled is best). Adding a "water wetter" does reduce the surface tension of water, which will help cool beyond a "normal" mix. But even that was originally developed for racecars first, and then passed on to motorcycles (bigger market ~ more profits).

Don't be fooled, there is no real difference between automotive and motorcycle coolants.

I have been riding for a good 10 years now, and i've always used car coolant in my bike. I rode a crf450 for a while and races=d tight hairscrambles and NEVER had a problem with over heating

if you spend money on "motorcycle" coolant,you are wasting money.Auto coolant with most already pre-mixed at 50/50 is more than adequate.

The thing to watch for is silicates. Try to use silicate free coolant. Coolant with silicates can wear your water pump seals prematurely. Of course my RM service manual doesn't mention this, so maybe it's not an issue any more. I always put only silicate free coolant in all my motorcycles. Better safe than sorry.

I was once doubtfull about using car collant in my bikes. anyway one day decided to use it. Never looked back, just mixed it 50/50 with distilled water.

although when looking for a coolant I looked for one that says

*does no harm gaskets or seals

just to make sure

I've heard that you weren't supposed to run auto coolant in your bike because it will corrode the aluminum. But most car manufatures use some type of alumnium part in there engine. For me I worked at a dodge/subaru. So I just jacked so subaru coolant
