2017 Kawasaki Ninja ZX-14R ABS SE. Öhlins rear suspension upgrade

I have to mention Mark and the help he provided me was second to none. he went above and beyond. I would love to do more buisness, unfortunately öhlins doesn't offer a front suspension for my particular model so I'm forced to go racetech internals at my local shop here in the Midwest. maybe you guys can poke öhlins and ask why don't you offer anything for the forks on an upspec 2017 kawasaki ZX-14R ABS SE? it's OK. I was amazed at the service provided to me. Thank you Mark!

HHR Performance

first off it's winter here in the midwest so I can't comment on the product yet. I'm sure it's going to be great. Mark! at HHR He is so good at his job! He went above and beyond for me and I appreciate that. Great communication and knowledge. Thank you Mark! I want to do more business but unfortunately Öhlins doesn't offer anything for the front forks of my particular model with the upgrade Brembos.. such a bummer. so I'm going to have to go to my local shop for racetech upgraded internals in the front forks. if Mark is a gauge on how this company runs is just fantastic. I been contemplating moving to Florida just to be near HHR. Keep up the great work!

I ordered the wrong item

I ordered the wrong item. When I receivedit, something didn't look right so I contacted these guys and they said they'd get back to me. They quickly did and they confirmed I needed a different item. They sent me the correct item free of charge. That's something you just don't see these days. Thank you.
