One big thumping rod of hard steel has always been good enough for me...

LOL.... dont think im telling you something ya dont already know here some how..... but, one of De Tomaso's 1st projects with Benelli (then owner of Moto Guzzi) had been to produce a single overhead cam 4cyl engine, in nearly every respect a copy of a Honda designe. In 74 the 350 version became the moto guzzi 350gts.

gezzz.... not my fult ya shouldent have mentioned the name Guzzi

I'd guess that no matter what type of 250 you got, you'd still find yourself wanting more grunt after a few months if you go on highway/open road rides with larger bikes. I'm a bit sick of the Zeal in that regard, having it constantly whining at 10-12,000 rpm and still not able to keep up with them.

Ive had twins and four cylinder bikes. Don't quite know about twins having more torque, must have missed that one. The Four cylinder bikes are by far a better bike and I seriously doubt that I'd ever get a twin again as my main ride.

I've never had more than three cylinders at one time. I prefer twins and singles, 4's are great but I just don't overly like them. I reckon the twins and singles have more soul.

So long as you keep a CBRRR above 14,000rpm, it's pretty damn fast, and if your at full revs and you let the clutch out smoothly, it does a nice wheelie, great bike so long as you don't crash it

Please tell...

Why did you think the four cylinder bikes were better?

Well, I am expecting that, but I would still have to ride a 250. I don't want to waste money upgrading, hence trying to find a bike that would have depth...

Not an option for me. The bike is too small...

Gremlin, The above should answer you as to why a 4 cylinder bikes is smoother.

In all honesty, I found my CBR250RR more than enough to get myself in to trouble. The difference between an inline 4 250 and a v-twin 250 would be insignificant to a learner. I took a Honda VTR250 out for a spin one afternoon and I didn't find it as good as the CBR. The CBR would be alot smoother and pull alot harder once you get up in to the REV Range. I did find the VTR not as scary as the CBR.

I guess it is all up to preference at the end of the day. You have to ride both bikes to see which is better.

Have a look at an inline 4 dyno sheet and a v-twin dyno sheet. That would tell you how and when the torque comes on.

The four is faster, much much faster. Also the power curve is much more impressive with that sudden increase at higher revs. I'm waiting for the day that I get the CBR600RR as it will be the bike I will stick with until I'm too shabby to throw my leg over it

At the end of the day everyone has their preferences and the inline 4 is my favourite over all the other engine types.
