About quality and texture: I am happy with the quality of the thermostat unit from SP Takegawa, a very compact design with beautifully finished parts from the machined aluminum housing to the alloy springs.
About the feeling of use: I feel my oil cooler system on the Grom is now perfect. After adding the larger SP Takegawa oil cooler the engine was slow to make it to the correct operating temperature but now with the thermostat installed that temperature is achived much earlier and then maintained once the thermostat opens to allow the oil cooler to operate.
Products to buy together: Some form of way to mount the thermostat unit into your engine oil system is required to purchase along side the thermostat unit. Either a SP Takegawa clutch cover or a inline thermo unit kit is needed.
Difficulty of installation: The process to install takes about 5 minutes, just needed to remove the thermostat hole cap and oil hole plug before installing the thermostat unit. Not difficult to do.
Cost performance and comparison with other products: Good costing as you are receiving a very useful part that has been well designed with quality finishes and don't see other brands like Kitaco offering a part like this for their oil cooler systems.
About shipping and packaging: The faster shipping options are too expensive for myself so I just have to wait for my part to arrive via sea freight. Webike kept me updated on the status of my order up to when it shipped. The parcel arrived within the expected date range and was well packaged with no chance of the part being damaged.
Any concerns, cautions, or advice when purchasing: I find the thermostat unit be to neccessary in the cooler months of the year here in Australia but definitely not needed in the summer months.
