just ordered an RX4, what to look out for

as the title suggests, i spent some time researching, found that the honda CB and the DRZ would be somewhat away from what im looking for and the RX4 strikes the balance im looking for, also monetarily, was looking at the hawk DLX my buddy has and was happy but as my truck had its major failure i shot for the RX4 instead after looking at the above two, any info or help is appreciated, i have seen the articles on the tires being very street oriented which is fine, any recommendations for a good highway/offroad tire?

Congrats on the new bike! Doesn't it come with Dual sports tires already?

The OEM tires are OK for street and some mild off road riding. You will see that the tread is kinda shallow for anything like mud or sand. I like Shinko 705s but they are really only a bit better than what came on the bike. You will get at least 5K miles off the stock rubber so you have lots of time to think about any upgrade. In the short term I'd consider changing the spark plug for an NGK and possibly installing a DID O-ring chain. As you get more experience on the bike you fill find other tweaks to make the bike truly 'yours'....like any other motorcycle. Welcome to the club!!

do you have a link to the chain kit, and what the spark plug number is

NGK ER9EHIX Iridium Spark Plug
DENSO IY27


CSC carries the NGK above, and a chain kit in DID as I recall, I have both, installed the NGK the chain is to be installed when needed. So far my original chain is fine.
Mine is a yellow 21 and is lots of fun.
There's a big RX4 thread on advrider.com, and the facebook groups for CSC, so both of those plus this site are must see's.

yes it does, but they are very street biased, i live out where its a good mix of dirt roads and normal streets (oil field country) so the more balanced tires is what im interested in if the ones on the bike dont feel too good, experience comes from a 125 yamaha YZ 2 stroke

Howdy TBONE !
I love my RX4 but find it is way too heavy for me in my Old age ! I'm not the strong short and stocky guy I used to be now I'm just short ! so I had an issue with it's height!
you wouldn't think it needs to be lowered but it did for me I lowered it 2" in the front and 2.25" in the rear and now I can flat foot it easily though to pull that off I had to Make a new lower link. complete with Bering bronze bushings !
I was concerned with top end speed on the bike but yesterdays Ride proved to me it will do what I want. I don't think I will ever take it to 90mph so the gearing seems ok for now....
I got rid of the foot pegs right away as I got the wide pegs for the Kids TT250 and liked them so much I got them for the RX4.... I can hit bad bumps and my feet stay put !
they didn't on the original pegs.
one bad thing I've found about the RX4 is the resale value I paid over $5000 for it and it seems even CSC will only sell it for $3500 that really SUX ! even if it only has 200 miles on it !....
selling it to a private party is the only way to go obviously !
.....
Bob......

Nothing special - just ride it. For the first 500 miles or so I did lots of short, hard pulls followed by throttle cuts for engine braking in order to wear in the piston rings when I got mine. Apart from that, I just rode it normally. No need to baby it. I followed the same procedure on my RX3, TT250, and SG400 also, without issue.

TBone:
to answer your question on brake in procedure ...CSC says just ride it, but don't lug it !
and I think that is good advice ! the bike was extremally TIGHT being new, don't be disappointed by it's power when you first get it as it does improve !....SERIOUSLY !
it is that tight internally !
so don't over rev it, and don't lug it.... use the transmition ! I kept the RPM around 5000RPM for the first 100 miles ... till it loosened up a bit ! and didn't ride it longer than 30 minutes at a time and let it cool before proceeding.
although I haven't even changed the oil yet on mine I think I will this winter just for S&G's.....

Also be aware that the tempiture gauge is off a bit.... CSC says it's generous ( indeed)
so watch the numbers not the gauge ! don't let it get any hotter than 94C it will hover right around 92C i think, so just take it easy on it till your first oil change ! it is SLOW to brake in in my experience.... but after the first 100 miles it started feeling better !
as for the tires I drive on paved back roads and the tires are good for that but I doubt they would be the best on dirt all the time Knobbies would be far better I think for that!
this bike has a very HIGH center of gravity with a full tank of gas ! it has fell over on it's side 3 times for me to my dismay ! it didn't hurt a thing but it is very embarrassing to be spit off the bike at a stop sign ! (that is why I lowered it a long way)
.....
it's a great bike....but heavy for me.... it reminds me of the Honda 1100cc shadow I had ages ago just too heavy to be comfortable !
...
at 70mph this bike is rather quick responding in trajectory a gust of wind will throw you around a bit, more than you'd think for such a heavy cruiser !
...
the ABS brakes scared the Heck out of me ! but I was only using the back brake
I found that if I used both brakes it reacted fine... just one brake though it acted like it let up and went free wheeling .... it didn't but I had to re apply and grab the front brake to not go through the stop sign ! so I recommend applying the brakes to the skidding point to see how it reacts it may well surprise you....it did me ! this bike wants you to use both brakes ! every time ! and I don't always do that.
....
hope that helps !
Bob.......

Delevery time for my bike took almost exactly 30 days and I just live 600 miles north of the CSC shop.... their delevery guy had to make 8 stops before he got to me and still had one more in Medford Or. I have no complaints as there wasn't even a single scratch on it
and it still had about 1/2 tank of gas and it was ready to ride when it was unloaded !
so no complaints at all on the RX4's delevery..... but it was a bit expensive. the Driver called me and said "I am about 5 minutes out are you home. and I said "I sure am come on !" LOL.... 15 minutes and he was driving away...

I had ordered an RX4 earlier and then there was the big shipping delay and CSC couldn't get the bikes in when they promised so I canceled the order, and I immediately got my money back... 2 weeks went by and they finally got them in so I re ordered
and after about a week of DMV paper work she messaged me and said it will be on the road to me in about another week.... so technically it took a good 5 weeks to get it after ordering it ! so I would plan on 6 weeks minimum from time THEY get them.
Sara there at CSC is a gem to work with and she explained everything very well.
she had 120 some odd DMV things to go through before mine... but she did it fairly fast !
they really do alot of business down there !
....
