Best warm to hot weather coolant!
I went through 3 coolant flushes to find the coolest running coolant. My temperatures were running very hot during the summer. Ambient temperature range from 95-110. My engine was running 225F with 30/70 anti-freeze/water & Redline Water Wetter. Switched to straight Engine Ice and reduced to 205F. 1 week later switched to straight Redline Supercool and temps are now at 198F quick idle, 180F freeway @ 100F ambient. This doesn't have anti-freeze but I never ride below 40F anyways. Anything with anti-freeze won't cool as well ex. Engine Ice. Bought all coolant from Cycle Gear, wish they had a return policy for failed coolant ;p. Bike: 03' CBR600RR

PROS: Easy to use, Runs very cool

CONS: Needs a bit more volume

good product
I replaced my original antifreeze in my 06 KTM 200xc. Although it never ran terribly hot, I would feel a good bit of heat coming through the shrouds after longer motos. Now, I don't even notice it, so it must be running cooler. I put this in 100% because I'm not worried about freezing temps here on the Central Coast of CA.

PROS: Cool running

Hot Ducati running cool
Ducati ST4 running hot, drained coolant and re filled with supercool. Temps are at least 10 to 15 degrees cooler. Stop and go traffic was 210F, now 195F. Also cools off quicker when speeds increase. It was worth the price for some peace of mind. Going to use in my Suzuki DR 400 and Honda CR 500 next.
