The first time was in a Nolan N102 modular helmet. This is the first time I installed one in a Nolan N104 modular helmet.
The first time around was very straight-forward. The unit installed very easily using the preferred clamping method.
Nolan has made a number of really important improvements to their flagship modular helmet since the N102 came out.
This helmet is substantially lighter, and is reported to be quieter as well due to the improved aerodynamics of the shell. The ventilation system is improved with the addition of rear exhaust vents and improved chin, brow and head vents. Last but definitely not least, beginning with the N103, Nolan added an internal sun visor. In the N104, they added an instant retraction feature.
The design changes to the helmet make the installation of the Sena system a little trickier. The main difference is a thermo-plastic fairing around the edge of helmet. The only options for installing the Sena are 1) to forego the mechanical clamp and use the glue-on interface. Like other riders, I prefer the clamp method; 2) cut a slot in the plastic fairing to slip the clamp plate in.
I know that installing with the preferred clamping method is possible, because others have done it before me. I'm just a camp follower adding my voice to the crowd.
I encourage you to check out Richard Machida's installation on his blog by clicking here.
Richard referred to a previous installation that he had followed on the FJR forum. You can take a look at that installation by clicking here.
To do my installation I used:
- A divider to measure the length of cut I would need to make
- A drill and drill bit
- A Dremel-type tool with a cutting disk
- A box cutter - craft knife
- A metal ruler
2. With the pads out of the way, I spent quite a while examining where I would cut the slit for the Sena clamp. The trick is to mount the unit as far forward as possible so that the boom mike sits in proximity to your mouth once the helmet is on and the face shield is closed.
3. Once I knew where I wanted the slit, I carefully measured the length of the required slit with the divider.
7. With a dremel-type tool and a small cutting disk, I cleaned out the intervening plastic between the line of holes.
10. The rest was very simple. I clamped the Sena unit to the helmet and tightened the screws. I then installed the speakers in the speaker recesses in the helmet. They were a near perfect fit. The speakers must be the same size as the Nolan Ncom speakers.
12. Finally, I re-installed all the padding and tested the installation. In a word, flawless.
13. As a last step I paired the new Sena SMH10 with my iPhone, and then paired my existing Sena and new Sena for intercom use.
I have a lot of experience with the Sena SMH10 and I recommend it to fellow riders without reservation.
With two Nolan Sena-equipped helmets, I may be able to convince Susan to try a jaunt this summer, on a nice warm evening, to get some coffee or ice cream.
One can dream.
