X7,s were either average or fast. I remember when my mate bought his in the summer of 78 and we would go out two up and his X7 would fly round the speedo to 110 mph which was probably around a true ton. Now bear in mind that we were both around 10 stone each. When I bought mine in 79 it would max out 105mph solo. The difference was in the finish of the ports from the factory fast x7,s felt like they had a stage one road tune.
@@billroberts5661 interesting comment, I remember it would be back in 79 when I was at collage, one of my mates had an X7 a few had X5’s and RD250’s But the X7 was the fastest of the bunch. The X5’s were only 200cc and were way slower than their 250 counterpart. It was amazing what a difference 50cc made. One of my mates had the original Dream 250 and even with some serious tweaking that topped out at around 85mph so the four strokes of the day were really no competition to the high reving two stokes. Then of course a few years later came the next milestone which was the RD250LC otherwise known as the widow maker. By that time I already got a driving licence and had already migrated to a sensible form of four wheeled transport. Great days, hanging out on a Saturday tinkering with our bikes, up to your elbows in grease and drinking copious amounts of tea and smoking way too many cigarettes.
I had a blue X7 in 1979-1980 And it was really fast, And; Maybe I'm a Really bad driver!!! But; if you had it in second at traffic lights and reveved It up a bit to take off and clicked down in to first, it would lift up on the front! Especially if you had a Pillian!!! Because it was so light for its power! The Yamaha RD 350 was faster bike! But; Too, many young men lost their lives on these in Ireland!!! Espeally Racing from Cork to Kinsale! Because; they were too fast and unstable for their power!!! It was Really Scary when your doing 60 and it starts to wobble!!! I know the Honda 400 4 stroke was a bit slower, But it was heavier and had a damper! And Therefore Safer!!! I Sold it in the end because I Ended Up with 3 Stitchs on My Knee! Which got Infected and I Ended Up having an Operation! So be Safe and Buy a heavier bike with a Damper! So! "Bugger That!" And; Save Yourselves from; "Geting Stitched Up!"
My friend Damien had one of these back in the day, as a fairly new bike. In standard tune they would do around 85mph, that's it. Nowhere near the ton. I had a CX500 at the same time and could easily roll the throttle back and go past once the X7 was at top speed. This one must be tuned.
My mates had one of these, extremely rapid 250s. Would not do more that 75mph when he first got it (carboned up std exhausts) Tried to decoke them, bike hit 80 mph then but still dissappointing. Ended up rebuilding the the engine, new crank, rebore, pistons & rings. I did some porting on it. Enlarged the exhaust port & raised them by 2 mm. Skimmed the head to bring the squish band down to 0.7 mm. K & N filters, micron expansion cans. Once run it flew ! Would wheelie on acceleration in the first 3 gears, up to 60 mph it was as quick as my Z750E (four cylinder) Topped out at 110 mph @ the red line in 6th. Sure it would have gone faster with higher gearing as it was still pulling and was about to go into the red on the tacho. (warned mate not to take it into the red as it may have caused the pistons to hit the head due to con rod strech at high RPM) Mate kept original gearing as the acceleration was fun in the powerband. Used to eat the yamaha LC250s that were supposed to be faster than the X7. Mate kept that bike for years, even when the rest of us went to 750s and 1000s. He would only lag behind on a run when speeds went over 100mph. Ah, to live those years again !
meinem bruder seine ging leider vor 2 jahren kaputt. sehr schönes motorrad, is richtig gut im hohen drehzahlbereich, von unten raus schwächelt sie etwas. Frisst n haufen spritt wenn du sie drückst
+fred krüger Hallo Fred, nein in beiden Fällen wird die Zündung unterbrochen. Der Schalter ist eher für einen Unfall oder Notfall gedacht (geht schneller als den Schlüssel zu drehen...) Gruß Axel
also meine letzte x7 hatte ich 1991 und die ging ohne tuning und ohne anlauf 170km/h. wenn man jetzt die offene version hat mit 32 ps sind 185-190 sicher auch ohne Tuning drin.
