im buying a rvf400 might sel the datsun dunno think my motor blew up tonight

i have one of those, very nice bikes, but as freak mentioned they are grey imports and thus hard to find parts for(in sa anyway)

just bkeep an eye on the cooling system,use a toggle for the fan if you have to..

NSRs are all grey imports and were restricted from 89 onwards. MC18 and up as they came from japan. Story goes too many accidents were happening on the early unrestricted model the MC16(pre 89). Top ends are as good as up 40000km if synthetic has been used its whole life and the bottom is good for 60000km before the bearings even need a look. To be safe you'd prob do the rings every 15-20k to keep it all fresh. For more peace of mind they are based straight from the NSR250 GP bikes and are strong as hell.

why were the nsr250's restricted? i know they now comply with the power to weight but when they were released it woulda just been under 260cc. how often does it need to be rebuilt and does it just need top-ends or full rebuilds? sorry for all the questions but i'm trying to get as much info as i can. thanks

Very easy to rebuild. Like a big whipper snipper haha. Thay come under the restrictions because they come limited to 45hp from japan. Get on NSR.com which shows how to take the restrictor of with one simple wire job for instant 65hp. Makes it the same as a aprillia rs250/susuki rgv. Infact mine used to pull away from a mates 03 rs 250.

yeh i'm dicing up between 2 stroke or 4 stroke, the powerband would be a lotta fun. in act and nsw the 2 strokes that come under the power weight limit are honda nsr250, yamaha tzr250 and the aprilia rs125. you can get nsr150's but i've heard a lot of stories about these blowing up quite easily. how easy is it to rebuild a nsr250? i'm doing auto at college pulling apart whip snips and mowers easily so i was wondering with a bit more experience i could do my own rebuilds.

Get a NSR 250. 2 stroke power, very reliable and a very quick 250. 65hp and 125kg, twin discs the lot. Way better value than a cbr ad you don't get bored of the power so quick. Honda claim a mid 12sec quater too. Oh plus they can wheelie I found it a great bike

yeh no worries mate, if you need any more info just ask, i might know.

Hi, It looks like the cbr I was looking at has now doubled in price and I am in no extreme hurry. I will look at any option. I love the honda reliability and build quality but the Italians have some great gear too.
Thanks for all the info . A little education goes a long way !

i'm getting my moto L's in 3 months and i'm looking at the cbr's as well. only the cbr250rr was officially imported into australia, all the rest are grey imports. apparantly the 1990-1993 models are the best as they have all the new chassis suspension etc but after 93 they were restricted to less power. also look at zxr250's (these are sometimes called zx-2r but all of them that have this written on them have aftermarket stickers) , these have upside down forks etc. and rev to 20,000 but i'm not sure how reliable they are. pm me if you have questions, i've done a bit of research in the 250/learner market looking for bikes myself.
lethal_john what aprilia do you have? i could be interested.
