I have a 2004 Honda CBR F4i 600 and I want to strech it. What parts do I need and where should I get them from. How much will it run me?

Custom frame work, third party forks… And your modified bike might not be as well-balanced.

Here's another idea. Sell the sportbike and buy the Honda Shadow cruiser that you really wanted.

Longer swingarm, longer chain, new front and rear sprockets, new rear shock, probably new rear wheel and tire, new rear brake hose, rewire rear lights. Rough guess $4,500.00.

Hi this needs a custom bike builder which will depend on who it is as to how much it costs you.

It depends on if you:

A) Plan to actually ride it.
B) Plan to go around corners.
C) Plan on drag racing it.

600 class supersports are designed for one thing, to go fast on a twisty track. We (friends an I) laugh at stretched 600s because you are essentially rendering the bike useless.

You're 16 and have no job. Forget it.

Need money and some equipment or more money to hire work. Base minor stretch sometime done for drag strip is the extended swingarm. Extra chain, extra long control rods and some cutaway on back fender-figure $1000.00 to do minimum. Might get luck and find a swingarm from another model or year that would fit with minimum work-- Kawasaki did basically that on the 500 triple 2 stroke after first 2 model years, road racing experience against Suzuki at willow Springs- next years model had 2.5 inch longer wheelbase from mostly extended swingarm, slight change in neck rake. Frame stretch may be possible, not difficult on steel tube frames with some straight sections in center- back of frame with swingarm mount gets cut, spaceing tubes added to cut and reweld - often with inner gusset to strengthen frame at the stretch. BMW /2s frame got the cut and extend when putting VW 4 cylinder engines in before the /5 series came on market. A few of the Rat Bikes made from the R's get that treatment or the splice 2 damage frames into one. Bigger seats, bigger fuel tanks can be used then. What happens when you have slow shop in winter, cheap parts available from the salvage yard that has hauled in wrecked cycles and finally gets insurance company OK to scrap or salvage. Check your local motorcycle salvage yard, local Honda Dealer for possible parts, parts interchange. Extanded forks- Fork tubes 2 to 4 inch longer and a neck rake of 3 to 5 degree neck angle will get you a inch or so extra wheel length- more stabil at street hiway speed, the basis for many old choppers works. Larger diameter front wheel will have slight effect but noticeable at cruising speeds where previously had twitch. Get a 600 Shadow, change VIN tag and put your license plates on it is cheap way.

Loads of elastic bands, $20 from dollar store.
