
Since the brake system of this motorcycle is filled with a glycol-based brake fluid by the manu-
facturer, do not use or mix different types of fluid such as silicone-based and petroleum-based
fluid for refilling the system, otherwise serious damage will result.
Do not use any brake fluid taken from old or used or unsealed containers.
Never re-use brake fluid left over from a previous servicing, which has been stored for a long
period.

ENGINE COOLANT RECOMMENDATION

RECOMMENDED ENGINE COOLANT
The factory filled engine coolant of this vehicle is SUZUKI super long life coolant (Blue). It is recommended
to use this SUZUKI super long life coolant when replenishing or charging the engine coolant.
SUZUKI super long life coolant (Blue) as supply part is already diluted to the 50 percentage with deionized
water. Use it as it is without diluting.
SUZUKI recommends to use following coolants in that order.
1) SUZUKI super long life coolant (Blue)
2)
SUZUKI long life coolant (Green) or equivalent
ENGINE COOLANT
Use an anti-freeze/engine coolant compatible with an aluminum radiator.
There are two types of engine coolant: one used after diluting with distilled water and the other used as it is
(without diluting). SUZUKI super long life coolant is the latter type and SUZUKI long life coolant is the former
type.
WATER FOR MIXING
Use distilled water only. Water other than distilled water can corrode and clog the aluminum radiator.
ANTI-FREEZE/ENGINE COOLANT
The engine coolant performs as a corrosion and rust inhibitor as well as anti-freeze. Therefore, the engine
coolant should be used at all times even though the atmospheric temperature in your area does not go down
to freezing point.
LIQUID AMOUNT OF WATER/ENGINE COOLANT
Solution capacity (total): Approx. 1 350 ml (1.4/1.2 US/Imp qt)
