Many Kawasaki H2 SX and H2 SX SE owners have reported issues with radiator damage, often attributed to stones being thrown up by the front wheel. The primary concern is Kawasaki’s decision not to include a radiator protector as standard. But how prevalent is this issue, and what extent of damage can it cause?
After just over a week with my new bike, I noticed two to three minor dents and one more significant damage to the radiator. Despite not hearing any stones hit, the damage was evident. This occurred while riding on relatively clean local roads around Munich, highlighting the vulnerability of the radiator even under seemingly benign conditions.
In response, I attempted to straighten the fins and subsequently installed a radiator protector. Although I had ordered radiator and downpipe protectors before acquiring the bike, they arrived late. In hindsight, my enthusiasm for riding overshadowed the necessity of installing these protectors immediately. Using a plastic stick, I managed to realign the fins sufficiently to maintain airflow, which was satisfactory. For those in a similar predicament, I recommend ordering protectors well in advance and installing them as soon as you take possession of the bike.
To access the cooler, both side panels and the surrounding fairing must be removed. This process is straightforward, but care must be taken with the plastic rivets.
Once the panels are off, remove the two bolts at the top and one at the bottom of the radiator to mount the radiator guard. The downpipe guard installation is slightly more complex, as it is secured beneath the radiator where the side panels attach with long bolts. Initially, position it provisionally, then reattach the fairings and secure them. For the lower side, use two washers and nuts over the bottom bolts of the fairing. Although a bit challenging, the end result is both sturdy and aesthetically pleasing.
