(This ended up being more than intended, but was just trying to give the best useful info )
Definitely the Reflex. (I have 4 of them I like them so well.) I am quite familiar with the Reflex. If you get the Reflex, we need a picture for you to show it off. (and pics if you need help with a problem) The 249cc Reflex is going to be faster than a Roketa with its 244cc engine having the vertical cylinder like a Helix engine. The Reflex engine cylinder is more horizontal.
I would consider Reflex scooters 2004 through 2007 to be about 5 or 6 hundred $$ more valuable than 2001 though 2003 because the newer ones have a better charging system. And I would separate them into those 2 groups and otherwise mostly disregard the year of manufacture and pay more attention to differences in mileage and mechanical condition. For example; a 2004 and 2007 of similar condition with the major difference being that the 2007 had 22,000 miles and the 2004 had 11,000 miles; the 2004 would be the more desirable bike.
But ask some questions. Why was it put away and not ridden? Was it in running condition when they put it away? Are there any other known issues besides the no start problem? How many miles on the bike and how many of those miles did they put on it if they were not the original owner? Did they or anybody else work on the bike during the time they owned it? If so, what was the problem and what was done to fix it? Has it ever been in a wreck? Was it left out in the elements or mostly been sheltered for the non-running time? (being outdoors may have had critters chewing on wires and/or building nests in unseen places... bugs are good for finding tiny places to plug things up) Are tires the originals or had they been changed at some point? if so then when?
But first tell us about the Reflex. Their asking price, miles on the odometer, is it the ABS model? ABS will have a slotted ring that fits closer to the axle just to the inside of the brake disk... one at the rear may be harder to see. A speed sensor on the caliper with a wire running up inside the cowling above the wheel. And there will be a red light on the tachometer. The title will show it as NSS250A or NSS250AS. The A denotes ABS, the AS identifies it a Sport model with ABS. If the title shows NSS250 then it is just the standard model. If it shows NSS250S, then it is just the Sport model. A Reflex with ABS is worth about $100-$200 more than one without it. No real used value difference between Sport or Standard models.
Minor damage just to the plastics is not truly an issue to be too concerned about since it is merely cosmetic. The main concern is with electrical and mechanical issues if any.
Mileage around 20,000 or less... no problem One of mine is already at 34,142 miles with about 13,000 of those miles using a car tire on the rear before it was moved to a different Reflex where another 20,000 miles were put on that tire. Taking a look at a Reflex forum and you can find that there are some Reflex scooters still on the road with mileage in excess of 60,000 miles. (not many scooters can make that claim... so that's saying something about the Reflex)
(inspect the bike if you can)
Sitting for a year means there is a possibility for rust in the tank. That is fixable, but it is a bit of a pain to have to go through all of that... even if you just need to change the fuel filter which is well up underneath the plastics. Look into the gas tank with a flashlight to see what you can at the bottom of the tank. Some rust spots is no big deal, but covered in rust means cleaning or replacing the tank to avoid rust clogged fuel filter headaches. You can expect things like small cracks in the tires from age but should cite that as a demerit in bike value and part of the price consideration. There actually is a way to determine the date of tire manufacture by looking for an oval imprint on the tire with at least 4 digits. first 2 digits show the number of the week in the year 01 to 52 . Then the next 2 digits is the last 2 digits of the year of manufacture. so, for example (2713) would mean it was made the 27th week of 2013; roughly somewhere around the first week of July 2013. Tires older than 6 years in age are suspect, especially since it has not been used... even more so if the bike has not been moved for that time (and may have developed a flat spot in the front tire from just sitting on it for so long.)
On the right side down at the engine is the oil fill. the plastic tab unscrews from the engine and has an integrated dipstick. With the bike on the center stand, unscrew the oil fill, wipe the dipstick clean and just reinsert it all the way back in, BUT DO NOT SCREW IT IN!!! That is the proper way to check the oil level. Pull it back out and just note if any level shows. No oil is not a good sign. (at best shows severe neglect) Low oil may not be too bad. If the oil is very dark, that's OK, Oil starts getting dark almost right after you put fresh oil in and mixes with the little bit that remains even when you drain it. But if the oil is brown and kind of goopy, then that is a problem as it means there is water/coolant in the crankcase. That is fixable too (maybe) but not really for a new owner who is unfamiliar with the bike yet. If that is the case then I'd pass on it... that would be a big job to fix.
So obviously it will need some work to get it running and rideable shape. Not a terrible thing if it is just not running for need of removing old gas and filling with fresh and replacing a battery, changing the oil and maybe putting on new tires. If you got it, then I would recommend a thorough going over; changing and setting gap on a new spark plug (depending on mileage and last stated tune up), changing the air filter if needed, changing out the brake fluid and engine coolant and final drive gear oil. Inspect the drive belt and replace variator rollers if they have developed flat spots, clean the foam air filter at the variator, inspect the clutch shoes for excessive wear, check for excessive brake pad wear and replace if needed. Make sure that all lights and instruments are functional and everything else on the bike works as it should. Getting all that squared away and the bike should be trouble free for a good long while and should not need much outside of the regularly scheduled maintenance items. Actually this all would apply to any used bike that you may happen to get.
Here are a couple lists of 2007 Reflex scooters for sale to see prices that are being asked (plus a few other vehicles that the sites forces onto the lists)
The caveat here as I had explained to a guy on another site looking at a 125 Zuma, these are the sellers
current prices and may not end up being the actual selling price. Some I would guess will be less. (If negotiable)
claz.org/classifieds.html?q=2007+Honda+Reflex&o=4and another list of 2004-2007 Reflex scooters for sale(a little harder to go through because some of the listings are no longer current)
www.searchtempest.com/search?location=48307&maxDist=3000®ion_us=1&search_string=Honda+Reflex&keytype=adv&Region=na&cityselect=zip&page=0&category=8&subcat=mca&minAsk=min&maxAsk=max&minYear=2004&maxYear=2007Some of those ads are just ridiculous and they'll never sell at those prices. There is not a Reflex out there worth over $3000 now (unless it is just out of the crate with under 10 miles on it)... and I don't think such a bike FOR SALE like that exists. But I wouldn't discount the idea of a collector having one like that. IMO $2650 would be the top $... and it would need to be a 2007 ABS Reflex in at least close to showroom condition and 3000 miles or less on the odometer. Everything else would be downhill from that.
In 2006 I bought a 2004 Reflex Sport with 2000 miles on it for $3000... not a scratch on it... all shiny black and sexy. And, back in 2008 I did get a 2007 Reflex Sport with only 632 miles on it for $1700 off of ebay. (in good used condition they were closer to $4000 back then) The prior owner Wrecked it and managed to break or scratch almost every piece of the body plastics. But there was no structural damage... Around $700 in new plastics later and I had a barely used showroom quality Reflex that cost only a little more than half its true value. And I still have it.
(though it looks nothing like it did before since I've been doing some modifications to make it into a streamlined bike.
