Cowardly Duck,

Thank you for the info on the Bermasters. I will have to do some experimenting with tires/tyres. I am curious to see what Hyena says about the Halo Contra. Checked out the prices on the net, they are 30-40% cheaper than the duro razorbacks. That alone is enough for me to take chance on them if I want to go to a dedicated offroad full knob set up. Anyway thanks again for the breakdown on the Bermasters.

Are the knobs bigger than the duro razorbacks that come stock on the new bombers? I like the rotor and calliper mods from Zero you have. Your fighter is really built for going fast, and stopping fast.

Yep, it's a bit silly making your bike go alot faster if it's not going to be able to stop faster too! Not so much an issue offroad as largely your own skill as a rider to worry about but if you stray onto a road by accident you need to be able to pull up in a hurry when cars inevitably disregard you!
I never actually had the razor backs, only crazy bobs so I can't comment on the knobs. They ARE pretty chunky though. When I first started building / modding this I wanted it to be the ultimate offroader but after putting a few miles on it now I very infrequently come across terrain where I really need the big knobs so I'm thinking when they wear out I'll go with something a little tamer. I'm tempted to go with DMR Moto RTs which I"m a big fan of on my other bikes - they're a great all rounder though if you hit a patch of soft sand or mud you could come unstuck. They're more along the lines of the berm masters, though quieter and lighter I'd dare say. They're quite balloony too so offer some extra cushness - not that I need it with the ride set up I have on my fighter. The only down side is a relatively soft side wall which may be more susceptible to punctures it something sharp and nasty flicks up.

Hyena, what are your thoughts on running the 3" on the rear and 2.6" on the front? Would I just be better off running 3" front and rear?

Bikes of all types often run fatter tyres on the rear for grip so I see no issues with this. I guess it makes the steering a little lighter but one way or the other it's not really going to make much difference. I don't ride close enough to the edge of the bikes limits or mine for it to be an issue.

Hyena, have you tried the DMR Moto Diggers, i liked the RT's i fitted on the Bomber but opted for the Moto Diggers this time for the Big Hit, they are good enough to do rolling stoppies in the wet on pavement and dont move around on the soft stuff anywhere near as much as the RT's did, granted they may not last as long as RT's but they are in my view a better dual purpose tyre. I have always used the wire bead ones not the fold ups.

Hyena, have you tried the DMR Moto Diggers

That's what I've got on the front Sounds like our collective experience and preferences have aligned across the planet
I bought a set with a plan to fit them front and rear but then decided to fit the fatter rear one.
I think it's actually them rather than the fatter rear that makes most of the noise on the road. I don't mind it as it sounds pretty cool (check out the sound in my ride by vids) so I might chuck the other motodigger on the rear when I pull the 3" fatty off. And yeah I go for wire bead where ever possible.

I do have plans to go larger again with a bigger motor, 18x2.5" motorbike rim and 4.1" dual sport tyre but that might be for another build I think

Just noticed a sale of bankrupt stock on ebay/amazon of 'Vuelta' 24"x3" downhill tyres. Bit of a gamble but interesting, given the general lack of such tyres on the market... Unfortunately, the sellers give few details and I couldn't find much info about them, but they look very knobby. Presumambly the company has now moved away from making tyres.

I ordered a couple and will try and give info on compound and tread/bead etc once I can compare them to the Razorbacks and Halos.

currently using these tyres on rear of my kona stinky,only 1200w cyclone power but really pleased with them at this price.

RST forks working well.
I have had my Bomber for a month now. I found that the forks were great with the large bumps, but the small 1"-2" bumps the forks did not move. I rode a few weeks to see if they would loosen up with use, but they remained stiff.
I carfully lifted the seals and sprayed silicone spray in and around the seals.
I made a huge improvement to the fork action. With the small and large bumps now being absorbed by the forks.
Because the fork tubes are alloy they have high friction with the seals and bushes.

I found the same thing with the RSTs and have just lived with the lack of compliance on the small bumps. I will be interested to try a bit of silicon spray on the seals. Thanks for the tip.

I also used the spray but it needs to be used every day. I then used Mobil 1 0-20 oil and it lasts a few days. I used a needle type injector to get under the seals.

I found that after 3000 miles or so the forks would rock back and forth a heck of a lot just by tapping the brake....look down the tubes and tap-tap-tap. That did not instill confidence at 50 MPH
Hell with that...lol

Bought a Fox 40 and now she rides....no see floats

Fox 40's are $1600 list is the only downside, I got for for $1500. I see Jim Kirk a Bomber owner has them for sale on ebay at $1100 http://www.ebay.com/itm/ws/eBayISAPI.dl ... 0824029330

[Stealth_Rider]

I'm the person Paul mentioned is selling my used Fox 40 on eBay. Here's the eBay link to my auction:

Paul previously mentioned my posts on installing a 13T freewheel on my Bomber and a Derailleur on my Fighter. Here's the links:

The RST forks are working ok for now, I just give the fork tubes a spray after I wash the bike.
I was considering upgrading the Marzocchi 888 RC3 Evo Ti Forks or the Marzocchi 888 RC3 Evo V.2 Forks, some feedback or a review on these forks would be great if you have used them.

Rear shock shaft protection. I noted on the Bomber that there is no protection from stones hitting the rear shock shaft. If the shaft becomes pitted, the shock will eventually leak, then you will either have to replace the shaft or entire shock.
I made up a foam protector, that attaches to the shock with 2 zip ties.

Can you please post a photo of your kick stand on your Bomber. My next project is to add a kick stand, so I am interested to see how you attached your stand.

Thats a great idea. It will easly tripple the life of the shaft seals. I bought a neoprene shock cover from lizards skins for my bomber when it arrives.

I used Gunk's liquid wrench dry lube on my dirt bike forks. Maybe its in my head, but the forks appear to be less sticky. I just spray the upper portion of the fork tube and compress the forks up and down before the dry lube dries to work it into the seals. Then I spray the uper tubes again and let it dry. Takes about 5 minutes. When it does dry, it will leave a white film. I think this may be better than using silicon spray on the RST forks because dirt likes to stick to silicon. That may advance the wear on the fork seals. I will try this on my bomber when it arrives and post the results. Too bad nobody offers a DLC kit for home applications.

We both use this kick stand: http://www.oemcycle.com/Products/Body+K ... ide_Stands

Shim the outer clamp with a block of 3/4" plastic wood and drill two holes and put a few screws to prevent it from working its way out. The stand fits like it was made for a Bomber and slides behind the rotor.

Thanks for the info on the stand and drylube.
I have some drylube, so I will clean off the silicone and test the drylube. I will advise the results after testing.

Should have gotten the Bomber....Fighters R fer Girlz

Welcome to the group.

[Marclink]

Very funny! I've been struggling with whether to go with the bomber or not I like the weight of the fighter much better but obviously the power of the bomber. All kidding aside their New York should I move up to the bomber?

Your in NYC?

I'm in the Bronx NY with a Bomber.

I think you are on the limit of weight for the Fighter, not so much for power but more so for rear shock compliance. The Fighter uses an air shock designed for mountain bikes. The Bomber has a motor cycle shock fitted.

If the actual weight of the bike is a major consideration for you, the Fighter is the right choice. You will need to run 200 psi plus in the rear shock though to keep sag under control. I am 200lb and 6' 3" and run 180psi in the rear shock. I think the extra 20lb you have on me will still be manageable but of course running higher pressures in the the rear shock means a slightly stiffer ride. You will need to order a shock pump so you can setup the rear to suit you.

In relation to power, at 3kW, the Fighter has plenty

I must have missed the weight bit but how much are we talking?

I loaded up well over 200lb total on my Fighter and it was fine, maybe not quite as nimble but it sure felt planted.

[Kepler]

Marclink is 220lb. Still should be ok I think.
