I currently have a RXS100 which I mainly brought as the GF needed a way to get around at summer so we went halfs on it. She didnt really enjoy the experience since we got a car she doesnt want to ride it and so no longer need a sub 125cc bike.

I like how the 100 is cheap to run but seems pointless to not get a slightly bigger cheap to run bike as I have a license (and its always nice to change bikes).

I have been thinking about getting a GPZ305 as reckon it will be a cheap runaround till I graduate (e.g. 65mpg, disc brakes, 95mph top speed, 6 gears etc).

Just wanted to get some feedback from owners/previous owners, I would like to spend upto £800 on one. Any other bike I should look at instead which would be better? Cheapness to run is more important than performance.

So, they good bikes? Seen a few on ebay and seems chain and sprocket conversion is done a lot and new 2 to 1 exhaust, guess the orginal rotted? Anything to look out on them when buying one?

Trying to save up at the moment so a sports bike is a not going to happen till Im out of uni Sad

Spend £500 on a CB500/GPZ500S. I liked the 305 about 15 years ago, I'd be surprised if there's many in a decent enough condition now.

I had one about 12 years ago. Was the most economical bike i've ever owned. Quite quick for what they are but turn nasty if you push them hard in the corners. 6th gear is an overdrive and they need frequent oil changes cos the heads wear.

Yea well going to sell the RXS and plan to put a little money as possible ontop of that to get something bigger.

Thinking the 305 over the 500 as reckon fuel/insurance could be a nice saving. Plus dont really need a faired bike. Seen these and both seems pretty cheap and good condition:

Sold but was up for £500

On ebay at the moment £500 starting

Wouldn't fuel be pretty similar as you'd be thrashing the 305 more?

If you have £800 to spend, for the love of god, buy something else. They're terrible.

However, mine's cluttering up the garden at the moment, so if you really really want one and you enjoy fixing things, make me an offer Wink

I use to enjoy fixing things but after the 6v electrics of the RXS I need to 100% working bike!!

£800 is my absolute max, going to sell the RXS and see how much I get and then try and get something for as little extra money as possible.

You got anymore details on the GPZ you have?

I have a 500s and i can't say it bad on fuel at all.

Much better than my hornet.

I get about 115 to a tank and fill it up about 13£ a time and i absolutely rag the living shite out of it. Twisted Evil Getting air over the speed bumps is fun.

Well, a 100% working bike it is not.

1987 with 36000 miles. Rear shock linkage is shot, and in pieces at the moment. The engine has a loud, intermittent top end rattle, possibly the cam chain tensioner, which has failed before, possibly because I was fairly inebriated when I last assembled it last and probably forgot something important. Carb floats jam sometimes too, I'm still not entirely sure why. I also have a spare engine, partially stripped down with a collapsed gearbox bearing, although it was running pretty sweet before. Chain conversion on both motors, although the one currently fitted has a welded front sprocket. Clutch slip on both engines. On the plus side, the front tire is almost new and I'm pretty sure all the electrics work.

If you really really wanted one of these, a new/rebuilt engine and new shock linkage bushes would see it on the road again for a lot less than £800, but honestly this bike is more trouble than it's worth, especially if you rely on it to get anywhere.

I would really wonder if these are now to old to be financially viable. It's one thing for cheap running costs, but if spares are silly money due to rarity youd be much better off with a cb/gs/Z 500 of more modern era.

Belt prices used to be horrendous, conversion to chain was common.

I think they had taper head bearings which are akward and expensive also.

Too many niggly faults that will cost you to sort. Just get a parallel twin that will do everything better for less money and a lot more reliably.

Have a look in the used bike bible for them, the concencus is that they were pretty terrible 20 years ago and haven't aged well. Cheap reliable transport they are not.

£800 will get you a decent 500. If you want cheaper simple wheels then any other 250 twin will do - CB250 is simple and slow, for example.

Agreed. Buy a GS500E for £800.

Never owned one myself but i did used to know a guy who had a few of them. All of them were knackered to some extent and unrideable. he couldnt make one good one because they all had engine problems. He was a bit of an enthusist about the 305 and even he said they were crap.

Buy a 500 CB/GS/ER or a 600 Divvy. I reckon the GS will be the cheapest to buy and insure, theres lots of them about so if you need any spares you should have no trouble finding them.

The GPZ500S is a damn good bike but will be more expensive to insure.

If insurance is your main concern, get a quote for all of them. The MPG will be about the same for all of them and dependent on how you ride.

I also heard that the GPZ305 has chocolate cams that pit very easily...
