I ride every day 20 years. Used Nolan flip up all those years and my wife. Replace helmets every 4-5 years. No problems till this one. 2 yrs into 5 year warranty, sun screen stops working. Sent helmet back to Nolan to repair. I paid shipping there, they paid return. Helmet works 7-10 days It fails again exactly as before. Send again. They pay both ways. "Repair" last 4-5 days. fails again same as before. I offer to buy new helmet at 50% discount. They say 10% discount. I say no. Send back third AND Fourth time, same result, same failure. I pay to return FIFTH time, they pay return, open box and sun screen slide is COMPLETELY FROZEN. I call, they say no more warranty, even tho only 2 years of 5 year warranty. I paid $60 to ship it twice, and all they could do was to insist it must be my fault.
Very good helmet , very comfortable to use. PINLOCK very useful in winter with the temperature close to 0 degrees Celsius , not the viewfinder fogging . For the value , it is an excellent cost / benefit helmet.
Having owned a Nolan N 103 previously I had high expectations for my new N 104 Evo. The helmet didn't disappoint. The shield is larger to allow better vertical and peripheral vision. The helmet is lighter and the ventilation system is improved. The noise reduction is better also. The only negative I have found is the latch system isn't completely padded to reduce chafing on my throat. Excellent helmet!
I bought an N44 1 year ago. It has good air flow for summer and seals well down into the teens. The sunvisor could be lower, but most sun visors are high. the B5 bluetooth works well, although at speeds over 75mph, it is hard to hear. I use the helmet without the chin bar in town and add it when on the highway. With a little practice, you can add the chin bar after the helmet is on. Best helmet for the money I have bought in over 20 years of riding.
