Hello Rider,
I've install those HD srping into my girlfriend's CBR 125 R 2008 6000km last week end. Its was a noticable upgrade. I'm very happy how's bike feel right now. Before spring, we had to lean over gaz tank to reach 120km/h. Now we reach 130km/h way more easily and even get about 140 if we lean like we did. I've did a air box snorquel mod as well.
I've had question before purchasing and Marvin anwser them quickly (like 15 min).
I had a small issue on installation that is not related to spring, I've email Marvin again (out of working hour) and he's response within 15min. 30 min later, few email and a new schemas Marvin sent me, everything was perfect and ride even better than its was.
Really appriciate dealing and learing about CBR 125 R with Marvin.
