More power!!!

[Daz1245]

Hello currently have a rf600r, and wondering what's the best ways to mod these motors?
Would I get best benefits from a engine conversion? If so does anyone know what engines swap straight into one of these? Or am I best just looking for a rf900 too end ?
Thanks

Just buy an RF900. It's not like they are expensive and it's less headache than doing an engine swop or trying to tune yours.

I would but I've spend shit loads restoring this into
What it is now and don't want to get rid of this as I love this bike

I was intrigued by this so figured I'd add some ..

The 600 is a short stroke, high revving machine 65 x 45.2mm (peak power @11500).

The 900 on the other hand is 73 x 56mm and offers bags more torque as a consequence (peak power @10000)

Swapping the top end (if it's even feasible) will not buy you that many more ccs and you're still left with a high revver - assuming you can sort out the carburation that is.

On balance a poor idea IMO.

I wouldn't bother. If you want a faster bike, get a faster bike. The RF600 motor is reasonably highly strung as it is, and is never going to be up to the technology of a more modern GSXR600. If you were to, say, buy a cheap GSXR750 SRAD, you'd see massive gains in both performance and handling.

The RF600 is not widely considered to be a good or special bike but you'll not get more from it without seriously hampering reliability and spending a lot of cash. Even the contemporary bikes of the time were better (such as the CBR600F etc).

You can pick up GSXR SRAD's for next to nothing at the moment, so I'd consider that... or if you've got a bit more to spend go with a K1 or newer. You will thank us if you do that.

Thanks for the advise, think I will keep the rf as it is and get another bike in the future, I have never had plans to get rid of the rf6 so will keep it standard

Intake/exhaust, jet kit, most likely amount to stupid £££ for small gains though.

Might be worth just playing with the gearing if you are looking to change it up a bit?

Disagree. Its a unique motor in the RF range, they look a bit like the water cooled GSXR 750/1100's but they seem to be different enough.

Im not aware of any easy ways to increase capacity of the smaller RF engine, and it won't really be supported well by tuning firms, a bit like you can get naff all performance parts for the ZZR600 engine compared to the ZX6R motor.

Its a shame you didn't restore a teapot GSXF 600, as with the old oil boilers you have several ways of increasing cc's and tuning for more power, to the extent that you could make one really embaress a std Bandit 1200 for example.

This is my rf600r it's been my project this year was a garden dump when I borght it, loads of new parts and complete respray and here she is, this is why I don't want to get rid of her

Tef, 100hp is not enough.

HTH.

I really like the looks.

Turbo-nitrous is obviously the answer.

I doubt the RF600 makes a genuine 100bhp. Maybe 80bhp on a good day.

I'd still expect 85bhp from it though at the wheel. Either way it should have been as fast as any other non ram air 600, FZR etc.

I've not got much qualified opinion, but I appreciate the 100bhp is enough to get around with reasoning.

The only big bike I've ever had that didn't have quite as much power as I needed at the time was a CB500S that was loaded up with a topbox and tent for a camping trip. I was using full throttle and most of the Revs several times on a winding and hilly A-road trying to get past cars going say 50-55mph. Probably more poor obs than gutless Honda though?

Wanting more power for easier riding, poorer planning or being lazy on, or just for thrill seeking is very different to physically not having enough power to climb a hill or maintain the speed limit etc.

If I wanted to maintain an average 100mph on a Sunday ride then I wouldn't pick a CB500 etc.

Alright, now for something that might satisfy OP's needs.

Try short final drive gear ratio, preferably with a short/quick action throttle. Both mods are cheap and easy to do.

I experimented with final drive gear ratios on my CB-1 and believe you me, having a short final drive gear ratio makes your motorcycle way more fun. Not necessarily faster, although the CB-1 was faster with the short final drive gear ratio (190kph+ / original ratio about 175kph). The downside of short final drive gear ratio is worse MPG and more revs all the time = more heat and I do believe more engine wear. But it sure turns a boring bike into a fun one.

Reading the specs, your RF 600 should do 235kph, imagine if it did only 220 but got there waaaaaaaaay quicker. That's what getting shorter final drive gear ratio is all about. IF your 6th gear is an overdrive, then it might even make your motorcycle faster than 235kph, if that's what you seek.
