Finally got wet

I've owned the NX for just about seven months now. Yesterday was the first time I actually rode it in the rain. That's not bad considering the number of miles I've put on it (~2000) and the number of business days that I've ridden it to work (since mid-March).

The Bike
I was pleasantly surprised by its ability to handle adverse conditions. It didn't feel much different than riding in the dry. I suppose that has something to do with the tires (Shinko 705). They handled the wet pavement with aplomb. I know to keep an eye out for pavement markings as the rain has a tendency to make them very slick. However, I never felt the bike slip or slide while riding over them. I didn't have any other issues other than my rain gloves slipping on the levers a little. I moved my hands inward, on the grips, to compensate for that. I noticed that I need to re-lube the chain, there's some surface rust on it this morning.

My Gear
Naturally, I had just washed the Olympia Bushwacker over the weekend. I chose to use the NikWax Tech Wash to clean the jacket and prep it for waterproofing. It did a decent job of restoring the color to the Hi-Viz jacket as well as removing most of the dirt. I plan to eventually use the TX.Direct Wash In waterproofing. I chose not to use it just yet because one bottle is supposed to be good for up to six garments. I only have two; my jacket and over-pants. Since the directions indicate one bottle per washer load, I figured I would use it once Fall arrived and the weather tends to be less dry. At that time, I'll wash the jacket, its waterproof liner and my FirstGear over-pants. The only issue I noticed was that my crotch was a little damp when I arrived at home. Unfortunately, that's common condition with waterproof pants. I don't know if the stitching has become loose with use or if the seams need to be sealed or if the waterproofing need to be "refreshed" with the TX.Direct. However, that was the only issue I noted and it rained steadily during my ride home. My helmet, an Arai XD3, is also very good at keeping my head dry. Water does not drip down the inside of the visor nor do the vents leak. I also put my Aerostitch Rain Boot Covers to use for the first time. They are pretty nice and very similar to Totes brand of overshoes. I like them because they come up to the mid-calf. This allows me to tuck my pants into them. With the over-pants, my feet and lower legs are protected from rain and spray. I read some reviews that said they were easily torn. I'm guessing this was due to a tight fit or operator impatience. So, I ordered one size larger than I normally would have. They were a little loose but not sloppy. They worked very well and I would recommend them. My Joe Rocket gloves, a birthday gift from a few years back, kept my fingers dry and warm. This was the first time I could recall feeling rain drops hitting the exterior of the gloves. No problems. The Seal Line messenger bag also did its job and kept everything dry. I opted to put my laptop in the messenger bag instead of in the Outdoor Research dry sack strapped to the rear rack. It made for a bulkier load but the bag isn't subjected to the spray, off the rear wheel, since it sits on the rear portion of the seat.

Traffic
For some reason, inclement weather seems to bring out the worst in commuters. Most are either afraid of the conditions or drive like idiots. I can't figure out if they're truly unsure of their abilities or if they've lost their collective minds. However, yesterday, everyone seemed to be on their best behavior. No one was in a big rush or tailgating or weaving in and out of traffic. Just a nice calm ride in less than optimal conditions. Kinda nice (if not for the rain).

Slow July

I haven't posted in a while because I haven't had much to say (no offense). The past month (July) certainly seemed to be either very hot or very humid or both. After starting out hot and dry, the weather pattern quickly changed to hot and humid (and wet). The lawn went from being slightly tan (dormant) to being pretty green (again).

I had an opportunity to ride, one morning, in the wet. It was not raining but it had been earlier in the morning. In an effort not to temp fate, I opted to put the laptop in the waterproof sack and I wore the liner in the Bushwacker. It was definitely a sticky ride to work. Granted, it was still very humid and the temperatures were in the upper 70s. So, I wasn't surprised to feel like I was in a sauna. However, while at speed, it wasn't too bad. Waiting at traffic signals caused the most discomfort. Naturally, it did not rain on me during the ride to the office. So, I still have not ridden in the actual rain while in the Bushwacker. Maybe some day...

The tires continue ti impress me. Although, I recently read a thread on Adventure Rider that indicated some are not all that happy with them. I have yet to experience any of the issues that were noted. They are smooth, hold a line in a corner and track on a straight line. The inmate that started that thread does ride a bike (Triumph Tiger) that's much different than the NX. Others chime in and it seems most ride something similar; Suzuki V-Strom (650cc or 1000cc version, I'm not sure). Perhaps these tires do well on lighter weight bikes. At 240 lbs, the NX is obviously much different than those previously mentioned.

The rear rack project is at a stand still while I'm doing a lot of work on the TransAlp. I discovered a leaking valve cover gasket, on the rear cylinder, during my ride home from purchasing the bike. There is some major dis-assembly involved and while you have all of those parts off, you may as well do some maintenance while you're at it. So far, the TA has new valve cover gaskets, new spark plugs and adjusted valves. The carburetors have been cleaned and I have bumped up the pilot jet sizes from 38 to 40 (not a big jump but enough to resolve some know idle issues). I have some new fuel line on order which will be the key to re-assembling everything. I also need to change the thermostat. After that, I can put everything back together and , hopefully, the TA will be good-to-go for years to come.

NX as an Adventure Bike?

As I've owned various dual sports, I've come to the conclusion that I prefer to ride dirt/gravel roads, forest service roads, two track and the occasional well-worn single track. I've never ridden motocross (MX) and really don't have much of an inclination to do so (no offense MX-ers). One of the reasons I sold my trusty DR350SE was due to the fact that it wasn't much of a on-pavement cruiser. Most of the routes that I would prefer to explore are usually some distance from my home. This necessitates transport (a tow vehicle and trailer or a pick-up truck) to the starting point and from the ending point. Sometimes coordinating that is as much work as the trip itself. So, I opted to buy something that can handle the distance involved to/from the start/end points as well as the trip in-between. The TransAlp fits that bill.

My wife indicated she was going to ride her scooter, to work, this summer. That prompted my search for a replacement since I used her scooter, to commute, last summer. Initially, I had a chance at a KLR250 but I was not financially ready to purchase so I decided to pass (ironically, I 'met' the KLR and it's new owner this past weekend). A few weeks later, I was put on the trail of the NX and here we are. After riding it for a couple of months now, I wondered if it could handle being an "adventure" bike in my sense of the word. Well, I had the opportunity to test the NX this past weekend in northwestern Illinois.

The weekend's activities involved an on-highway trip to Freeport, Illinois. That's about 90 miles of high speed pavement. The NX did not like that at all. I believe the gearing and the jetting both are culprits here. The tachometer indicated 7250 rpm @ 55 mph. I know the engine can spin faster than that but I prefer not to run those rpm for hours at a time. Additionally, the NX's 125cc motor doesn't have the torque to pull up (moderate) hills or deal with a headwind. Up hill into a headwind really causes the motor to labor. I wonder if the main jet is too lean because being at WOT (wide open throttle) didn't help much and fuel economy fell into the upper 80s (mpg). Perhaps if the jetting was richer, there wouldn't be the issue with hills and headwinds and , perhaps, the NX could make better use of the lower, numerically, 15/48 gearing. Regardless, those changes won't make the NX the long distance cruiser that the TransAlp can be (125cc single versus 600cc v-twin).

I was impressed by its ability to carry the necessary equipment. I put a waterproof bag, containing a tent, air mattress, light-weight sleeping bag and a few other odds & ends, on the rear rack. Additionally, I had a tool roll attached to the rack but the seat bore its weight. I wore a backpack with more gear inside which included a Camel-Bak reservoir. The NX handled very well considering the extra weight. Another pleasant surprise was my choice of tires; Shinko 705. Not only were they good on the pavement, they were equally as good on the gravel. They didn't handle the small amount of mud they encountered but I did not expect them to. However once back on gravel, the sipes cleared quickly.

So, back to the original question; Would the NX make a good 'adventure' bike? I think not. It was certainly fun to blast around northwestern Illinois, especially on gravel, but the fact that it won't cruise long distances makes me think it's better off sticking to (mostly) commuter duty.

Ring out the Old

I was really hoping to get a season's worth of riding on the original equipment tires that came on the NX. They're the ubiquitous Bridgestone Trail Wings, TW41 in the front and TW42 in the rear. Some folks refer to these tires as "Death Wings" due to their dearth of grip in off-pavement conditions.



When I owned a DR350SE, fellow owners hated them and would remove them, regardless of condition. I was fortunate, my DR350SE came with Dunlop D607s. They howled on pavement but I got good wear and gas mileage out of them. I eventually sourced a second wheel set for some Pirelli MT-21s and replaced the Dunlops with some Kenda K761s. I loved both; the MT-21s were great off-road and even on-road they were good (in the wet, too). The Kendas were pavement only, smooth and quiet.

I digress, I found the Trail Wings to be pretty good on the pavement and got good fuel mileage to boot (~94 mpg). However, at twenty-two years old, the carcass can begin to breakdown which would lead to catastrophic failure. While that's not necessarily bad in the dirt, it's going to be very bad on pavement, worse on pavement and in traffic. So, I opted to purchase some Shinko 705s from Motorcycle Superstore.

I ordered them on Tuesday, June 21, 2011 and received them two days later (!!). I don't care where M.S. is located, that's some fast handling & shipping. What's sad is that the Bridgestone's still look great, there aren't any cracks or splits and there's at least 1/4" of tread depth left. However, I'm not willing to take the risk (on having them fail massively). The Shinkos were $92 for both (on sale as of this writing) which included free shipping. They mounted up easily and the only issue I encountered was that the front Shinko (90/90/-21) is slightly wider at the tread shoulder than the original Bridgestone (2.75-21). This caused some interference issues with the front fender/fork brace. I had to reform it to clear the new tire.

I took them for a spin to scuff them in. I did not notice any difference in smoothness/vibration but they do ride much more quietly. I've seen several reviews, both on M.S.'s web site, on TransAlp.org and on AdvRider. Most agree they're a good value and wear slowly. I would hope they'll last a while and should based on the light weight NX. They have wide, deep sipes which should allow them to clear any mud quickly (although, I doubt I'll have the NX off-road any time soon) and prevent any hydro-planing. The rest of the week is supposed to be warm/hot and dry. So, I'll have ample opportunity to fully scuff them in before extended gravel riding on Saturday, July 2.
